TempleOS. All other operating systems are sinful.

Mac OS. People say it costs more, but I am not paying for a hardware and then some software that tries to make use of it. Instead I’m paying for a well thought out product that just works.

Linux of course. I don't invite Apple or Microsoft into my computer. Apple has good hardware though so I can understand using a mac.

Windows 7.

It was the peak of windows.

It was slick. It was fast. It was stable, and it was super easy to use. Never had a single problem with it, and unlike past windows OS's it didnt require regular reformats to clean house for stability.

Unfortunately its dead now, and Microsoft abandoned that approach and switched to a slow burn approach at walled gardening.

I use Linux now, have been for years, because I saw where microsoft was going when Win10 was in previews, and there was no way I was going to be part of it.

I use EndeavourOS. I like pacman and AUR, as well as the fact that Arch-based distros are well-supported by most software. I'm too much of a noob/too lazy to setup an OS without a GUI installer though, which is why I prefer Endeavour over Arch.

I'd just like to interject for a moment. What you're refering to as Linux, is in fact, GNU/Linux, or as I've recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux!

Windows because I know how to use it.

Linux because Linux

macOS and I like that despite how closed it is you can find new features, commands, apps and cool facts any day, I am gonna start to log all the good shit it has because my brain can't keep up LMAO.

Debian. Been running debian stable on 99% of my servers at work. And debian testing on the desktop, and daily driver. What orginally made me switch from redhat 7 was how frequent i ran into rpm hell, and how difficult it was to do an inplace upgrade. When i could just dist-upgrad to debian woody and everything worked, with a few well documented tweaks, I was sold. And have been running Debian on everything since 2002 ish.
It is stable, reliable, and dependable for the most critical applications. Truly the universal operating system for me.

Mac OS

It’s pretty, functional, and has unix underneath so I can use it the way I really like to.

I don’t have a favorite, use the best tool for the job.

Linux by far because of the customisation abilities it offers

MacOS, so easy to use that even 5 year old me had no trouble using it. Also because of how reliable it is, my custom PC running Windows has crashed more times in the past year than all the Mac’s I’ve ever had combined (since 2007)

Debian Linux on the server: all the flexibility I need in a server OS.

macOS on the desktop: it just gets out of the way and lets me do my job

plan 9

I don't actually have the patience to run it, mind you. But it's definitely my favorite in principle.

Whatever the fuck my brain runs. It's done a pretty okay job keeping me alive, and that's worth something, right?

Debian 12 runs all my servers. It's like the pinnacle of stability.

Amiga Forever…I always wanted an Amiga

Paranoid Android back in the android 4/5 days slapped hard.

Windows 95 and Debian were my “holy crap this is cool” operating systems as a kid.

Windows slowly went to hell over the years, and Debian didn't, so now I mostly use Debian.

Linux.

But of course I need a desktop UI too so that alone isn't enough. I don't have a favorite though.

Windows has a decent core and good core UI, but makes it awful with win11 UI and product pushing.

Ubuntu has or had PPA for selective more direct and up to date software, but I guess with the newer package distribution formats (flatpak and the others) I guess that's not necessary or a comparative upside anymore.

The UIs I tried or used on Linux I never really liked. It was reasonable or acceptable at most. I wonder if there's one I'd like out there.

My favorite OS is Gentoo Linux.

The main reason being that you have full control of the system, from the kernel, init (OpenRC or SystemD), to the different packages.

I've also found Gentoo to be very reliable. (I've had some bad experiences with distros like Void with KDE Plasma freezing/crashing).

It's a rolling release distro, but with more stable package versions, unlike ArchLinux. However it also gives you the option to use the lastest packages (By adding them to accept_keywords)

And if you want you can experiment with different setups, for example using musl instead of GNU's GLIBC, or using clang as the default compiler instead of GCC.

Arch, because the documentation and support is really good. And it 'just works.'

When it comes down to it, the only difference between distros is basically just the package manager right?

Arch Linux all the way. I love the AUR, the Arch wiki (though it applies to a lot of distros) and customizable it is.

I’ve had a Mac for a few years, but the Linux « itch » came back and I couldn’t scratch it with macOS.

Now I see just how snappier Linux is compared to Windows or macOS on the same hardware and I really don’t wanna go back.

Fedora for its stability. Arch for its customisability.

Debian 11 for my personal server, openSUSE tumbleweed for my personal use. Debian for stability and openSUSE for the latest and greatest of KDE plasma desktop environment!

Qubes OS

The virtual machine workflow has made me completely rethink how I use computers, and there's huge security benefits of compartmentalizing your digital life through Qubes. Qubes OS successfully compartmentalizes your VMs and brings them together under one unified desktop, so even though you have several VMs running, you can see all of them at once because you see their windows as if it was a regular Linux desktop.

There are some issues with it though, such as lack of 3D acceleration for gaming, and its rather picky hardware support. Along with needing hardware that supports Linux drivers, you need a crap ton of RAM (I'm running 20 GBs on my Thinkpad T450s) for all of the VMs you run at one time. It doesn't take as much CPU power as you'd think, though, as it uses Xen's PVH emulation, instead of full-blown virtual machines like you'd see with VirtualBox.

However, if you have the right hardware for it, and you don't mind dual-booting or using another machine for gaming, I urge you to give it a whirl.

Linux Mint. Just works. Zero hassle. Zero shitfuckery.

Been daily driving Pop OS with the Xanmod kernel for a couple years. Love it.

Arch Linux

So that I can brag about using Arch Linux.

Seriously though, I wanted to learn about Linux and chose trial-by-fire. I've used other (Debian based) distros but pacman + the Arch user repository are hard to live without now.

Though if I ever had to reinstall I'd probably save myself some headache and install EndeavorOS.

Daily driving OpenBSD for 1 year and 8 months now. The simplicity of it and its sane defaults make it much easier to configure than the Linux distros I've used in the past, and it has been more reliable than FreeBSD on my main system. On my X230, It Just Works™.

Nobody in here talking about BeOS, QDos, Geos (like windows for the C64!), AIX, or OS2 Warp? For shame!

QNX fucking rocked, I wish it had been useable as a day-to-day system. If I had to pick one it would be that sighs wistfully

Currently running fedora, because it is stable, easy to use and just works. Also, gnome is imo the best designed major, full-featured desktop environment that exists out there (even including windows or macos).

You might get a more tailored experience with window managers but im currently to lazy to set that up. I did use dwm for a time though, but it wasnt really flexible enough for me.
