Ubuntu is really a beginner distro. I'd much rather use Debian than Ubuntu. And yes, I prefer Fedora over Ubuntu. I've tested or daily driven just about every distro out there worth it's salt, including QubesOS, and I always come back to Fedora as my main daily driver. Fun fact: Linus Torvalds uses Fedora as well. In the end, it's a personal preference. Daily drive it live off a USB stick for a week or run it in a VM and see how you like it.
