The small performance boost isn't the main reason most people install these distros instead of Arch, they rather have to spend hours reading the Arch wiki and instead want a GUI live boot installer, preconfigured desktop environments that just work with NVIDIA, built-in gaming-meta-packages that make gaming on Linux more bearable.

I just recently made to switch to base Arch from Cachy so I can run Omarchy without any issues and it did take several hours of extra setup just to have a working system but it is nice knowing how to do it now.

I understand, but this distro doesn't bill itself as an "arch but for noobs" or something of the like like EndeavorOS does. It puts performance first and foremost, and I'm also making the (dangerous) assumption that Arch was chosen as the base for its reputation of being fast, up to date, and light, and not for any other reason(s).

Gentoo exists, and has been popular with those that simply enjoy the idea of their systems being slightly better optimized. There's really not much else to it.

I dunno how many people stick around with gentoo for the speed. It's main strength is extreme flexibility and customisability.
