I'm not too huge on basketball, but it is fairly fast paced and you can see some crazy stuff here and there. Baseball is one of the worlds slowest sports, so I just can't get any interest. It's kinda a bad comparison to make really. Do you like really slow and dull where the players actually just sit there chewing on stuff, or do you want something fast paced?
Basketball, there is just a lot more action, and a lot more flair, it's easier to watch, and a lot more fun to participate in
I HATE watching baseball. Playing it can sometimes be fun, but it's torture watching it even the MLB finals or whatever it's called. Basketball on the other hand is great. Playing a delightfully fun game of bball with friends is like sex and watching NBA or college basketball, while not always great, is still a lot better than baseball.
