There aren't. Kind is more stable, is more JS-looking and less Haskell-looking, which makes it more practical IMO, has a super fast JS compiler and you can write React-like apps on it easily, but some work is needed to improve the type-checker performance when certain syntax sugars are used. The core's performance is superb, though.
Idris2, I can't comment much. All I know is that I envy its unification algorithm and synthesis features. Its syntax is more haskellish, if you like that. It seems less mature in some aspects, though. Very promising language overall.
