This is how I feel about Gentoo too but I use Void as a daily instead, no systemd and it feels more like what Arch used to be (e.g. Runit is like 5k SLOC whereas systemd is 100s of k’s).
Not bashing but everything seems well engineered with less cruft/bitrot than Gentoo. Of course there’s less customisability xbps-src is pretty decent at doing the job, or just write your own templates :)
