Gentoo's bugtracker is still a great place to look for patches in case building something is broken, especially on the more obscure architectures like PowerPC, but the distro itself went downhill long ago. I've been a Gentoo user for over a decade, but I won't advise it even to my sworn enemy today. I'm using Void now. Never had an opportunity to check out Arch.

Gentoo historical, Arch "reliable"
In more recent years Arch has very much taken that place for me, it's clearly where a lot of the tinkerers are and collectively keeping their notes, and I've even used stuff that's Arch-based myself when there's nothing Debian-based that makes sense at the time (ex. on my Pinebook Pro). But I have to keep an article on my *personal* wiki just to explain to myself how to actually sanely do package management on Arch, ironically one of the things the Arch wiki can't really be trusted with :P
To grumble for a moment, it's especially annoying to me that the Arch wiki goes at length to insist people MUST upgrade their systems regularly and I'm a fool living in a fantasy land if I expect it to be even possible to keep using a system if I don't constantly keep up to date — which, uhh, goes at real cross-purposes with me using Arch-based installs for weirdo devices I don't use consistently, like my Pinebook Pro whose matte screen I find most useful actually for outdoors laptop work during the summer months . . .
