I mean, is it really worth it to compile every single program that I install? Wouldn’t that be a waste of time? I am inclined to try it out but on the other hand idk
The question you ask in the title is a more general one that you ask in the title.
Yes, Gentoo is a good choice.
No, it is not worth compiling every package. This should not be the main reason you choose Gentoo.
Admittedly, I started with Gentoo for the same reason (per-package compilation), hoping for performance gains. However, I stayed because of the excellent documentation, the great user community; the rolling versions; the customizability and control I have over my system, the choices I need to make when installing, and keep making as the install is continuously set up over the years.
I’ve tried quite a few distros over the (+20) years of Linux-use. I keep choosing Gentoo.
Arch has great documentation, rolling release, and customizability, minus the compilation. Obviously, use Gentoo if you want to. But for advanced Linux users, I highly recommend Arch.
As a long time Gentoo user I tried Arch a few times but the whole AUR mess instead of using the same tools for distro, community and my own packages really put me off.
Use an AUR helper.
The fact that there are so many of those is part of the mess I mentioned.
