I feel like that while this trio all look the same appearance-wise, it apparently was intentional given they're based on Fuujin, Raijin and Inari, referencing their types. The Therian formes were something I didn't see coming but I feel they definitely gave them some new uses in battle, especially Landorus being a great physical attacker, Thundurus as a fast special attacker and Tornadus being the balanced one.
My fave of the three is Thundurus, mainly because it's blue and it has the coolest-looking of the Therian Formes as well.
