I have heard that for a long time, but lately since the Red Hat and RHEL thing happened I have heard it more.
I’ve never given OpenSuse a try, not really because I don’t like it or anything just because I’ve been fine with my current distro, but I’ve been thinking about it and I’ll possibly install it in a VM and if I like it I’ll install it on my personal machine.
The only thing that really concerns me are the Nvidia proprietary drivers, they are installed during the installation when it detects my hardware or I have to install them manually?
Edit: After a while playing with the VM I decided to install it on my PC and my goodness, it’s great! Among the things to highlight, I find it incredible that they have things like Yuzu or RPCS3 in their available repositories, in my previous distro I had to use flatpak for that or appimages and many times those programs did not recognize my GPU (possibly because I used Wayland). I also love that it has apparmor installed by default and even that I can access snapshots from grub!
Plasma works really flawless on Tumbleweed for me. I never tried Fedora, but OpenSUSE is a lot better than Ubuntu for me. Less bugs and you always get the latest versions. NVIDIA driver is really easy to install: there are official repositories, they are updated just like any package. I think among the traditional distributions Tumbleweed is the best one.
