Pokemon is better, in my opinion. I liked Digimon, but I never got into it like I did Pokemon. I have every single Pokemon game, I have a tote full of Pokemon toys from when I was little, and I still play Pokemon to this day. Digimon was good in its day, but the only thing I ever acquired from that show was a T-shirt that I stopped wearing years ago. I also stopped watching the show years ago. Now, the new episodes of Pokemon do suck, but I still like the games a lot, so I think that counts for something.
