The time I spent “distro hopping” back in high school was because I didn’t have the balls to commit to a single distro. Even then the only time I actually switched was when I made a config change that blew up in my face so badly I needed to reinstall anyway.
If you’ve found a setup you’re happy with, by all means, stick with it. You’re not missing out on much by not voluntarily erasing your boot drive and installing an entirely new OS every week or so for no reason other than it looked cool.
(If you’re about to suggest dual booting multiple Linux distros, no. Just stop. I tried that once. You would not believe how many issues are caused by sharing a ~/.config between two systems with slightly different versions of the same software.)
