This is hard, I like Arcanine a lot, but I have to go with Charizard. It's iconic from the anime as one of the most colorful pokemon personalities Ash ever met with, if not the most, and it has 3 cool stages- Charmander, Charmeleon and Charizard, whereas Arcanine is just 2, Growlithe and Arcanine. Also, while some people hate Charizard for the fan service it has receive, it was made into a force to be reckoned with having multiple megas and a gmax form, and I did enjoy using it.
