I've tried another FSF Approved Distribution and it is surprisingly good. The test computer was a 4th gen Intel board with iGPU. Linux-libre did what it could to mitigate and it managed to do well. It's a 4rd Gen Intel CPU and microcode patches don't exist for all the vulnerabilities. 5 are mitigated by Linux-libre, 3 require microcode patches and one is just there. Perhaps there are other exploits but I didn't install this to be secure.

Performance is great and I would definitely recommend this to anyone who wants a FSF distro. It's Guix and I'm enjoying it. It's not like every other distro unless I'm using a terminal. I haven't compiled and tested my usual software for it yet. It feels very solid and mature. I used Trisquel for a few years and I might use Guix for a few years too.

Tl;dr I have been testing a FSF Approved Distribution and it is really cool. Skip their other distros and pick this one. It is one of the few Linux distros that really impressed me.
