I think Christian's will always be the best because it is the original. Her version is more sensual.
Dove Cameron's is very upbeat, fun, and cute. It's something I could definitely dance to.
I like both a lot. :)

Christiana wasn't part of the Disney corporation anymore when she released the song.
As far as I know the other girl is still part off the Disney " family" so as to stay within the U/PG rating.
