I have very little experience with Arch. I ran Mint for a decade before coming to Fedora KDE for Wayland's wider support for variable refresh rates and such.

A lot of my opinions on the matter have more to do with KDE vs Cinnamon. But as for Fedora vs Mint/Ubuntu/Debian, I have one major one: Software availability is nowhere near as good.

On Mint, a shit ton of stuff can be found in the APT repos, plus Flatpak is there. If the package you want isn't in either of those two places, there's probably an Ubuntu-style PPA (remember those?) or, if you're resorting to downloading and compiling from Git, they always include Ubuntu instructions and they work.

On Fedora, the standard repos via DNF have half a moldy butt in them. They maintain their own Flatpak repository, and there's Flathub. There have been a number of times where I've had to just give up having a piece of software I was used to because it's not packaged for Fedora. Build instructions are rarely written for Red Hat/Fedora, and "Well I'll just say DNF install instead of APT install" is usually "cannot find package."

I'll probably be moving on at some point, but it's working for now.
