Firefox

I used to but it got bloated to hell and back.

I use Brave as a second browser (mainly to separate different activities) and did not have any issues with it apart from dragging tabs between monitors (it creates an additional empty tab sometimes when doing this). Turned off all unnecessary stuff right when I first launched it and that's it. No bloat, no issues, just works. Didn't know about this CEO controversy but seeing as it was a long time ago, don't think it's a valid reason to not use Brave. And both logo and name are cool.
It's a solid option which we don't really have a lot of in open source space

qutebrowser ftw

Honestly, I only use it for when a site will not work in FFX-based browsers

I only use brave for iOS because it is the best there is
