Totally feel ya on Mint. I put it on my X230 just now because I wasn't planning on booting it up too often and didn't want a massive update causing issues down the line. Super stable, super user friendly. I always recommend it to newcomers. Lovely experience!
Haha yeah Tumbleweed is an interesting name. Suppose it's because it's always "rollin' rollin' rollin'". Constantly in motion!
I'd caution against it on low-data capped internet plans for instance, because it updates fairly often, sometimes 1GB or more. But also plenty of people update like once a week and it's good. I update pretty much every day. It's kinda compulsive for me and I like to see if anything is fixed or new. :p
So that's one cool thing it has over *buntu and friends: Newest and shiniest features, but they've been tested a bit more thoroughly than on something like Arch, and if it does go bad, you can boot into a "snapshot" and wait until a newer update hopefully fixes whatever borked it.
But I haven't had to roll back in ages. :)
I like keeping on the edge of KDE6 right now because it's improving very quickly. Same with Wayland, even though some programs are still fussy with it. (You can have X11 and Wayland both, and choose which to use upon login)
