In about 4+ years using Softlayer, I didn't have a single problem with them. The bill at the end of the month was reasonable for the amount of servers and traffic, and even one time where an errant worker on our app generated terabytes of wasted bandwidth and our bill for that topped our monthly one, they figured out a way to make it go away by pooling out bandwidth from all the servers together. They could have easily forced us to pay it. I guess its all down to personal experiences, and mine was great.
