OK, after about 3 weeks of running KDE, I’m convinced I made the right decision in switching over. I’ve had really good experiences both here and on my VMs (Arch and openSUSE, mostly). There are still a few quirks that I’m not able to work out, though:
Sometimes when I start up from a clean boot, my Activities are just…gone. If I switch to them via keyboard shortcuts, they reappear (and my startup programs that I’ve setup for each activity are launched). But the system has forgotten the activity name and background. A logoff/logon will bring the activities mostly back; see below.
Speaking of backgrounds…is there a way to use (1) background for all activities? This was doable with workspaces, but I can’t find a setting like that for activities.
One other thing that gets lost - well at least partially lost - are my pinned apps on the task manager. Any app that’s been pinned exclusively to (1) activity is lost, others work as expected.
