When CPUs were a lot slower you could genuinely get noticeable performance improvements by compiling packages yourself, but nowadays the overhead from running pre-compiled binaries is negligible.
Hell, even Gentoo optionally offers binary packages now.
Yes, I tried it around 2002/2003, back when the recommended way was from stage1. I think I had a P4 with HT. It was noticeably faster than redhat or mandrake (yes, I was distro hopping a lot). Emerge gnome-mono was a night run. Openoffice about 24hrs.
Lots of wasted time but I did learn how to setup some things manually.
Most of the reason to build your own packages is a form of runtime assurance - to know what your computer is running is 100% what you intend.
At least as a guix user that's what I tell myself.
Compiling your own packages only ensures that, well, you're running packages that you compiled. This definitely does not mean that your computer is running what you intend at all.
Half the time I don't know what my CPU is executing, and that's code that I wrote myself.
This is true of all programming
