I personally find them much more enjoyable to handle, calmer and easier to watch. If your looking to buy a morph, they can also be more interesting pattern wise.
I love the color of corns, but they arn't as good for me to handle as my bp. If I feel like handling a snake, I go straight to my ball.

They also get a bit bigger if you like the girth-size more.

On the bad side, they arn't nearly as good feeders as corns. They just usually have more problems and tend to fast. They also are very shy and can have stress related problems if they're in too big of a cage, too open (no covers on a glass cage) or temps aren't perfect. They are a bit more picky about things. :]
