I just installed Debian with Plasma, and have been using a system with Mint and Plasma as my daily driver for a few months now. I used the default Cinnamon for about a year. Plasma is definitely way more polished and allows almost everything to be done via menus which is NOT a given with most Linux things. It does work most of the time but expect to run into some basic task you didn’t even think about on Windows and having a frustrating experience chasing solutions to untangle how to do it.

I’m never going back to Windows but the amount of times I’ve had to do something convoluted to attempt something you’d think would be easy is too damn high.
