Gentoo. Gentoo users have pretty much supplanted Arch (btw) users in the "annoying poweruser" niche.
I agree with you a bit on Garuda, even as someone myself who uses it. I've had it break multiple times on me, I still use it mainly because it has all the stuff I like by default (and a cool dragon theme, which should be a requirement of all distros).
Other than that, I'm gonna be boring and say Ubuntu. Just a worse Debian.
