Pokemon
Digimon
I kinda preferred Digimon as the monsters look more badass and the anime has more depth than a little boy that chases endlessly to win a damned league.
The characters in Digimon actually grow up which is interesting to watch.
Monster Rancher is better than both of them
There was an anime about this and one of the main character was an one eyed monster right?
I like them both, but I prefer Pokemon. That series has better games.
Digimon is fully better in every capacity bar marketing.
