I was using Mint with my Nvidia GPU for a while but found that games felt very laggy. Not sure what was going on but I switched to Kubuntu and that seemed to resolve the issue. (I assume the problem was something to do with cinnamon).

I like KDE and feel like the tools are more mature than they are in gnome or cinnamon anyway. Snaps are annoying but are fairly easy to avoid.

My vote is for Kubuntu for new users.
