Pokemon: The anime is pretty dull and filled with fillers that are unnecessary for us to watch. But the games are freaking AWESOME.
Digimon: The games are pretty good, and they don't focus on only one type of gaming. And the anime is alot better than Pokemon's. Since they actually ahve a storyline that fits perfectly with the episode before.
IMO: Pokemon: games
But that being said, I enjoy both, so I won't let myself getting bothered by Digimon vs. Pokemon since I enjoy both very much.
