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.
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.

Hell, even Gentoo optionally offers binary packages now.
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.
Do you audit all the code before compiling? Otherwise you’re just transferring your trust elsewhere.

This is true of all programming
