Every time this is asked, I post the same comment. I used Kubuntu for years and liked it, but more recently they started doing things that annoyed me. The biggest was related to snaps and Firefox. Now, sandboxing a browser is probably a great idea, but I wanted to use the regular deb install, so I followed the directions to disable the snap install and used the deb. However, Ubuntu overrode that decision several times - I'd start browsing, then realize I was using a snap AGAIN. Happened a few times over a couple years. If it happened once, eh, maybe an error, but it happened 3 or 4 times. I came to the conclusion I wasn't in control of my system, Ubuntu was.
I switched to Debian and am happy with my choice.
