You think that the animations might have something to do with the differences? Shortening them in developer mode might help.
To an extent, but Samsung Experience, which I like a lot, is just a naturally clunky skin.
I’m not bothered by these differences. Sammy has come so far from TW and the Note is such a great device that it’s okay if it’s a bit awkward at times. This is true if it’s form factor, which I don’t like. But that’s how much i like the software.
