5th Gen Favorite Trainer Class out of These?

Yeah, these are the ones on my trainer card, so I was just wondering, which one would you pick?
Which is the best?

Pokemon Ranger, Pokemon Breeder, Scientist, Hiker, Roughneck, Preschooler, Youngster, and Ace Trainer.

I think Pokemon Breeder is the best, he looks like a total boss, but for some reason most people pick the ace trainer. I don't even know why, I mean... he has blue hair. And he has a long body, too.

This actually doesn't have much to do with the Fifth Generation. If anything, I'd say that they are more of a Pokemon General Gaming sort of topic.
