MK8 Deluxe is the most notable improvement over the original. All DCL. A fixed battle-mode. Jumping from 720P-1080P. Plus the local multiplayer works very well with the Switch concept. Rayman is arguably worse on Switch. Captain Toad is a bit more awkward without the gamepad. With most of the others the new content doesn't improve all that much on the original, and Bayonetta doesn't really add anything as far as I know other than running slightly smoother but without any other improvements.
