I would have to say Cynthia. She was most involved through out the Saga she was in. She was involved with skirmishes between Team Galactic, to me she seems like a hands on Champ. Although I like Lance he appeared as more of a officer of Pokemon G-Men more then the regional Champ. I did like his hands on approach as well again Red Gyrados, and vs. Team Magma and Aqua. Steven was in one episode... And didn't really do much at all, so he is definitely at the bottom of my list. Wallace has more of a presence in Sinnoh then he does in his own region. Not to mention he is seen more in a Coordinator role then a Champ role. I really don't care much for Wallace he shows up as in DP Saga and does Coordinator stuff not interesting in my mind. Then there is Alder, we have only seen him in a flash back of Trip so we really don't have much to go off of. Hopefully we get to see him Route 5, and hopefully he will be an involved Champ like Cynthia because he sure was in the game.
