Tumbleweed. I've used Linux since the nineties so I know my way around but I appreciate a sane default desktop install so I don't have to waste time fiddling too much.
People always talk about lean/fast/customizing, in reality most distros are performant and fairly lean/bloat free, it's just how Linux is. TW is no exception and like all the others it's easy to customize. I don't use YAST.
I can get comfortable almost any distro, though I prefer those with systemD+Wayland and Nvidia drivers in a repo so they update with the rest. I like rolling release, also considering the pace of Wayland and KDE development.
For new users I always recommend Mint.
