I used wayland for a long time some years ago and it was basically the same experience,
Screensharing was the main blocker back then.
Never noticed a difference in terms of snappiness or tearing.
Nowadays I have a nvidia gpu and wayland + proprietary drivers has tons of issues, so I switched to x11.
I could probably use the integrated gpu (amd) to drive the desktop and use nvidia purely for ai/ml (which would free up some extra vram) but then I can't play videogames on the nvidia card.
I get all sorts of weird artifacts on the screen, sometimes I keep seeing a still image of a previous window.
I didn't use sway though, I accidentally logged in into plasma wayland and noted the issues. I doubt it's caused by Kwin though, it would likely show up on their bugtracker.
