One that might be controversial: OpenSUSE Tumbleweed. I still have a lot of respect for this distro and I really wanted to like it but it’s just not for me. It’s the fact that major updates could occur any day of the week, which could be time-consuming to install or they could change the features of the OS. It always presented a dilemma of whether to hold back updates which might include holding back critical updates.
So rolling distros aren’t for me, everyone expects to run in to some occasional issues with Arch, but TW puts a lot of emphasis on testing and reliability, so I thought it might be for me. But the reality is I much prefer the release cycle and philosophy of Fedora, I think that strikes the best balance.
That didn’t exist when I tried TW, but that’s something I’ll at least try out on a second machine at some point.
