There's a lot of work involved in breeding either species. Making sure the females are of or above proper weight, having all snakes in good health, making sure you have an incubator (or two) and a good quality t-stat to keep the temps stable, having the room for the hatchlings and a venue or two to sell them once they've fed enough times, and of course, being prepared for health issues.

Corns are easier to breed and keep, but they can become egg-bound, so you have to be careful with them.
Balls need very stable egg incubation temps and more room as hatchlings than corns.

As long as you've read up, know all the minuses as well as pluses, and are prepared for all avenues, then go for it!
