OpenSUSE Tumbleweed is a rolling-release distro, so it has up-to-date packages unlike Debian where the packages are years out-of-date. This should make stuff like flatpaks and snaps much less necessary, since these are basically work-arounds for ancient packages.

Also, KDE seems to be very well supported on OpenSUSE, whereas it's more of an afterthought in most other distros, including Ubuntu and Debian.
