Linux mint is a common recommendation but I think a bad one (for beginners anyway), I highly recommend bazzite with kde, I have 15 years of linux experience and am willing to do infinite troubleshooting if you add me on matrix (which is on my profile) I’ve onboarded many people and this is my experience with beginners
in short, linux mint is bad vs bazzite with kde for 3 reasons
kde is much more well supported and developed than cinnamon, it’s not even close especially if you care about security
immutable distros are much more forgiving for new people, immutable means that the core OS can’t be modified.
and finally bazzite has more up to date software, linux mint is a “stable” distro, stable in the linux context means unchanging, not unbuggy
if you don’t know what any of that means, go bazzite over mint, you’ll have an easier time.
i have given linux to many many people at this point and neither of these things have been problems, when’s the last time you used kde?
