I really like Mint + Cinnamon in general, but it was getting really old earlier in the year.  I got new hardware and had to use Fedora + Cinnamon for a while on two machines and grew to like it.  Wish I'd tried it earlier.
It just about as polished... some things are more polished, a few things less.  For example, Fedora doesn't have the nice package update GUI that Mint does.  But, I typically use the CLI with aliases to update anyway, so no biggie.  DNF seems to be getting better than apt, though I had to write a script to force my mirror to California instead of anywhere in North America.  Firewall now happier.  So I've mitigated the Fedora issues.  I'm trying out things like systemd-boot and UKI.
All in all, getting new tech, kernels, Python X+1, and apps up to *two years* earlier is a big gain in my book.  I need to use flatpak even less.
