I don't really know Bakugan. I've heard of it, yes, but that's all. So I definitively prefer Pokémon; it's part of my childhood and I used to love watching the anime (the first ones were epic, today it's just crap, I think)when I were a kid, and playing all those awesome games (which I still like to do). And Bakugan....Well, as I said, I don't know very much about it and I'm not interested in it.
Pokemon, my favorite. Ash: Slowpoke, I choose you! *pokemon comes out* slowpoke: slllooowwwpppoookkkeee.
Yeah, definitly pokemon, I have pokemon pearl, even pokemon red, and blue (first pokemon games).
As much as my little brother loves playing with his Bakugan toys, and I like watching the show ( meh ), I honestly prefer Pokemon. I have been around it much longer, and I hate playing Bakugan video games.
Bakugan used to be really good, but I think it just keeps getting farther and farther from its original a bit too fast. Plus the bakugan like Drago just keep on transfroming. Pokemon is getting farther and farther from its original but at a more steady pace. Plus you don't see a Pokemon evolve more than 20x!!
Not a huge fan of Bakugan, nor am I a fan of the newer Pokemon. (Generation six, I'm looking at you.) But the original Pokemon media was fantastic and original. Bakugan on the other hand, a little bit of a copycat. I did try to get into Bakugan, and it still really didn't do anything for me.
I choose pokemon over bakugan. I once tried to get into bakugan but i just can't its just like yu gi oh to me. The only bakugan i know is drago. Pokemon was so easy to get into but i really don't play it like that anymore.
