(I mentioned most of this in another thread recently.)
I couldn’t fully get on with TW when I tried it because of very large updates appearing at random, which is due to its rolling nature. The problem I had is I would see a massive load of new packages that I didn’t have time to install, and I would wonder “can I leave this for now or is one of those a critical patch?”. On Fedora, my distro of choice, it’s a no-brainer, I just do the upgrade every night and the big version update twice a year when I’m ready. On TW you have more of an entanglement of major feature updates and regular essential patches which are hard to separate out. I prefer the predictability of Fedora, and the release cycle gets the balance right of not having to wait too much to get the latest stuff.
Just to be clear though, overall I think OpenSUSE is a great distro, I’m being critical but it still probably would be my second choice.
