I've spend the last three years using Arch daily and I was not really happy about it. After realizing that in a X11 system I would not be able to use mesa without installing Wayland I took the Gentoo pill, generic packages are garbage and you should build everything from source. Now I have -wayland in my USE flags and mesa builds without issues.
Gentoo is not really hard, you just have to understand how package management works there, portage is a very elegant solution for the "source based" question. It gives you an insane level of flexibility and control over the system, OpenRC is much smaller and nicer than systemd, and everything is rock solid, Arch always felt like a hobbyist project, while Gentoo feels "production grade", Bluetooth problems I had in Arch (probably related to the Kernel) doesn't exist in Gentoo, the information in the Gentoo handbook is very precise and usually things just work. I've always been in search of a distro like this where you can basically do "anything" and yet keep your environment flexible and small, in all those years it's the first time I felt true satisfaction when dealing with a Linux environment.
