Keyboard shortcuts have been a big pain point, but I'm adjusting. I'm using Plasma 6, and trying to use the defaults vs emulating the mac shortcuts. Print screen as a screenshot button makes considerably more sense to me than Command-Shift-4, and Meta+Print Screen captures just a single window.

Logiops + Plasma's multi desktop support has given me something very similar to the multi desktop experience I had before, and the pager in the taskbar is a big improvement.

The tiling in Plasma needs work. I initially loved it until I released that when I arranged the tiles differently on one desktop, it changed them on the others... Hopefully that gets better.
