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.

I must admit I've mostly been an Ubuntu user since about 2007. But switching to Tumbleweed was like a breath of fresh air. A lot of the things were different, but accumulated experience over years allowed me to feel at home. I used YaST once or twice, you don't need it at all.
