I have the Framework 13 and am currently running the COSMIC alpha on Pop!_OS. I love my current setup, but have tried Fedora Kinoite as well, and also had a great experience. Apart from running a few commands to get the fingerprint reader working, I haven’t really had to troubleshoot anything. Its been a solid experience from Day 1.
I’d recommend everyone to buy a Kobo over these, its much easier to read your own .pdf and .epub files than on a Kindle.
