I was not thrilled with Cosmic after upgrading Pop! but switching DEs on Linux is very easy so it wasn’t a huge issue. I think Cosmic could be cool given more development, it just needs time. Though Pop! making it their default seems like a bad idea for them, its one of the beginner friendly distros that always gets recommended to new Linux users and now that’s going to be their first impression.

Originally I switched just because I didn’t have a Windows install available and Linux was convenient enough to just download and stick on there. But then once I got used to using it I massively preferred it. I’m the opposite of what you’re describing, I don’t want “problem solving and tinkering”, I like Linux because it basically just does what I want it to do. Windows does what Microsoft wants it to do lol.
