Mostly positive althought there has been no shortage of bugs. That said, when I did a clean installation (not an upgrade), most of them disappeared, so I guess I’d recommend a fresh install. I still wouldn’t say it’s as stable as Gnome or Cinnamon, but the trajectory KDE have been on when it comes to making their DE less janky has been amazing recently.

There’s been a lot of subtle UI improvements that make KDE feel a lot less disjointed, although you still see it here and there.

The improvements to the overview (Gnome activities view clone) are great.

Compared to the absolute shit show that was Plasma 4 and 5 for their initial releases, Plasma 6 is amazing. It’s still not my DE of choice, but I keep it on one of my systems just to see the progress.
