I'm not an Ubuntu doomer like most of the internet (I don't hate snap like everyone else), but I did recently switch to OpenSUSE on my gaming laptop and I'm loving it. I switched because I wanted a rolling release distro so I didn't need to worry about waiting for new features. I also wanted to switch to KDE Plasma after using it on my Steam Deck and loving it, but I could have done that while staying on Ubuntu. It was just another excuse for me to try something new.

That said, I will likely never move my server off of Ubuntu. I am totally fine with my packages being old and not getting new features right away because my server must be functioning all the time. Even updating to new LTS releases makes me nervous.

Anyway, if you're happy with Ubuntu, don't let anyone bully you off of it. It's really not bad. It's stable. That's its best feature. Unless there's something specific you want from another distro, stick with what you like.
