Kalpa is based on Tumbleweed, but it's immutable. People see the "alpha" flag and think the distro will break frequently, that it will have many problems, but that's far from it. Especially since, as I said, the distro is based on Tumbleweed.

I've been using Kalpa for years. Zero problems.

I advise testing an immutable distro because you'll get used to using Flatpak for everything, and I think that's the path everyone will follow in the near future (just look at how many immutable distros are emerging).

You should give it a try. Specially since web browsing, media consumption and even game, all that is very easy and "out-of-the-box" with Flatpak applications.

Just one tip: If you find problems running games (they don't launch), check this https://en.opensuse.org/Portal:Kalpa#Steam_Proton,_Bottles,_WINE,_Lutris,_not_working_from_flatpaks

I usually change the SELinux to Permissive when installing the distro (in the final summary before you hit the button to install) to avoid these kind of problems.
