My thinking on this is that Debian isn't necessarily going to be that different. Sure, Gnome instead of Cinnamon, but Mint is based on Ubuntu which is based on Debian, so a fair amount of the base is the same.

Arch is rolling release, different package manager, and whatever desktop environment you want, so a lot different.

Tip: if you follow the arch install guide, you'll type in a bunch of commands, and get Arch booting to a command line, then have to look up what to install for a desktop environment. And while that could be fun, you could also type "archinstall" instead when you boot up the arch install disk, follow the prompts, and have it do the whole thing for you, including putting on a desktop environment.  

Or you could go with something Arch based. I installed the XFCE version of EndeavourOS recently in a vm, and it seemed pretty nice...

(Or there are plenty of non-Arch, non-Debian/Ubuntu options, of course...)
