I don’t use sidecar but I'd wager it's not as smooth nor optimized. I use it with an older iPad so newer version might be better at it, but I see some artifacts on scrolling sometime, and it's clearly using the iPad's resources at full. There are params like resolution and processing that can be adjusted to priotitize what you care about (e.g. I go with retina res and more latency/lower processing). I think sidecar will be better at the thing it does, I use duet mainly for the fexibility.
