Personally I don’t really hate Ubuntu, but I tend to find that everything it does, there’s something else that does it slightly better.
For example, it’s supposed to be a good ‘beginner’ distro or good for something that ‘just works’, but IMO things like Mint or Pop!OS do it a little better these days. Snap is supposed to be a nice simple way to manage packages without worrying about dependencies, but Flatpak does it better and so on.
So yeah I don’t hate it, I just don’t see any particular reason to really use it. Opinions may vary though of course.
