What I mean is that, when trying to find software for Linux, nearly everyone has an option available for Ubuntu and apt. The same isn't true for Tumbleweed unfortunately. You can fuck around with Fedora rpms when SUSE doesn't have an option but I had some issues with some software I use regularly. I still think Tumbleweed is an excellent distribution, I just find that installing the software I need is most frictionless on Ubuntu distributions.
Which software you didn't find on tumbleweed?
Packages that aren't native to Tumbleweed are available in Discover as Flatpacks.
You're probably trying to look for software "the Windows way" of downloading the sw from a website in which case you mostly see .debs and .rpms but that doesn't mean it's not available in the tumbleweed repos or Flatpacks if you search Discover.
Niche stuff not available in the official repos or Flatpacks can be found in the OPI(similar to Arch AUR) where the proprietary codecs also are.
I think about this less by using kubuntu.
I open Discover in KDE Tumbleweed, search for the SW I'm looking for, click Install, and then type my admin password to confirm. Don't even need to open the command line.
What did you find difficult in that?
