Dangerous opinion, I’ve recently moved to Fedora after Ubuntu and after customising it on the GNOME desktop, it’s literally Ubuntu (But better) in every way except no snaps.
Personally as someone who got the ground running using Ubuntu as my 1st Linux distro, fedora is a comfortable transfer and I really like their spins.
Sure DNF can be slow but you can fix that and sure redhat can be a little… difficult with their decisions.
What do you think of Fedora? So far I enjoy the stability combined with near-arch levels of getting new updates!
I recently switched to Fedora after roughly two decades of using Ubuntu (started with Warty Warthog), Debian and their derivatives. Feels oddly comfortable, and strangely nostalgic having started using in Linux with Red Hat 24 years ago. I think both Ubuntu and Fedora have their issues, as well as their strengths. It just boils down to what issues and strengths are most important to you.
