I’ve been able to run it on systems for years on end without them breaking/

One big advantage of openSUSE Tumbleweed compared to other distros (especially rolling release ones) is it’s package manager integrates with BTRFS snapshots so if something does break due to an update, you can roll back to a previous snapshot and still have a usable system and plan what to do next. One of the very few times that things actually broke in Tumbleweed for me (and many other users) I was able to roll back to a snapshot that wasn’t broken, waited a few days, than updated to a release that wasn’t broken.

Also, a more personal reason but I started with openSUSE (11.4 to be specific) back in 2011, so it’s always felt like home whenever I use it.
