i switched from gnome to KDE two days ago and i LOVE it. Love to customize stuff, the control it gives me. just upgraded to 6.1 on my fedora 40 install. Everything working perfectly, no bugs yet!!
edit: I have sicne switched to Cinnamon and love it even more :) been using it for almost half a year and am definitely staying with that.
I have nowhere near the experience you have, but remember giving Linux a try like a decade ago, and promptly gave up…
Tried again half a year ago, this time with a little more patience, and successfully transitioned fully! Rocking Mint 21.3, and loving it!! Even my printer works, even the bkuetooth receiver for my Soundsystem!! couldnt be happier!
