JBoss is totally subscription-based and it's less costly for us. As a solution architect, I would say licensing is key. The cost involved in implementing the solution is a key factor now that most companies are looking to cut costs. WebSphere is really costly and less flexible. I think the JBoss subscription is quite competitive. Most people understand that the EAP kind of solution will save a lot of money in terms of licensing.
JBoss has less maintenance costs than, for example, IBM.
