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!
AFAIK the uBlue stock image is even leaner than Silverblue. uBlue doesn’t contain any pre-installed Flatpaks by default.
Wait doesn’t ublue have the gnome apps installed as flatpaks¿? I have always rebased silverblue to ublue because I have had trouble with the ublue installer - some efi issues in grub
