As a distribution, I can say the same. I've been using Debian steadily for a few years now, and I have to say I'm happy with how well it runs on Power. Since version 11, they've improved the overall distro, and now it runs very well on Power. Unlike Fedora, which always has major problems of various kinds, Debian is always stable and runs well. Now, however, I've noticed that Ubuntu has finally achieved excellent stability, and they've finally fixed those major bugs that plagued that distribution for years. The great thing is that performance-wise, Ubuntu is truly the best I've seen on Power. So now I run perfectly on both distributions.
