FINALLY!
I like them both, but I have always liked the old regions more, so I would have to side with Kanto.
Music - the Hoenn soundtrack was absolutely AMAZING!!
Wild Pokémon - http://www.youtube.com/watch?v=FtDpNeWQoO0
Elite Four - http://www.youtube.com/watch?v=y1hBm4LRZRw
(it's terrifying, a bit - plus, the Elite Four here have THEIR OWN THEME!)
Elite Four Encounter - http://www.youtube.com/watch?v=OfTKlWev4jI&feature=related
(it's when you talk to them - freakin' scary! Imagine how GREAT it will sound when they re-do Hoenn!!!)
