sadnehs Really the only two things I'm missing is the hot corner in the top left of Gnome (the rest of Budgie is too good, I don't want to use Gnome on this distro). And I would like Wayland but that's probably minor.
What you say makes me believe that you would be very happy with the Plasma DE. All the happiness of Solus, plus the "hot corner" and Wayland. Not to mention, enough configurability to make it everything you could ask for, e.g., true fractional scaling that the GNOME-based DEs can't provide.
