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.
Hi! Thank you for the reply. The link in your comment does indeed work.
Try opening this comment in Avelon: https://lemm.ee/comment/1870509
It contains a community link that does not work in Avelon. Does work in some other apps. I'll try writing it on an emtpy line next in this comment, to test if Avelon then recognizes it. That is, if it's something in the surrounding text in the linked comment that might be the issue.
