I probably like this game's combat more than most of the series's. The command leveling and melding made it so that I was regularly upgrading and changing my moveset to keep things fresh, which I really like.
Storywise, it could've been better. Terra and Ventus both had interesting plots related to themselves but Aqua's is pretty much just devoted to following them around without much agency. This is somewhat balanced by her playstyle being my favorite one, but it's still a long time without much of an interesting story. I will say that this game does a better job than most in the series when it comes to tying the disney world plots and the main plot together.
