Digimon has the best tv series, pokemon has the best game series and YU-GI-OH has the best card game.

Pokemon by a landslide because of Team Rocket. I just love them lol. 

The original Pokemon. 

I like both shows a lot, but Pokemon leaves a bigger impression on people IMO. So Pokemon all the way.

I prefer Pokemon, and always really will.
It's got much more of a history with me.
Don't get me wrong, Digimon rocks. I just didn't get into it until years after Pokemon.

Pokemon. But I thought even up to Sinnoh region it was great. Original was awesome, and so were the movies.

I watched Digimon in the morning before School where as i saw Pokemon in the afternoon but if i have to choose 1 i saw digimon is a better show and pokemon is a better game/movie. Idk know about manga because i never seen a digimon manga or book. Here are my game problems, In some digimon games, they go back to lvl 1 after digivolving, but pokemon just keep lvling untill lvl 100.

i forgot to mention that i also saw pokemon/digimon when it had new eps

Funny enough Digimon was invented first in the form of little pocket device pets, they then decided to change it around the same time Pokemon was fleshing out and the anime was booming. Bad time to do a revamp I'd say
