Anything "immutable"
- ublue family: Bazzite, Aurora, Bluefin
- Fedora Atomic family: Silverblue, Kinoite, ...
- KDE Linux (experimental)
- OpenSuse MicroOS (for servers, but possible to add a desktop)
- SteamOS (limited hardware compat)
Any other answer is outdated and wrong.
Edit: holy shit the amount of mint recommendations is crazy. Stay away from mint, it sucks. It's just a less reliable version of Ubuntu. If all you like its desktop environment, that's called "Cinnamon", and it can be installed in other distros.
I think it's more that Electron apps can be written in javascript, and there are way more javascript developers than any other kind. So you're naturally going to see a lot more javascript software.
So it is, quite literally, a skill issue.
