Overall, bags are intended for the crowd that wants to have good ride quality, low maintenance, and an overall functional system. For hopping, 3-wheel motion and more operational time, hydraulics works better. Since I have a limited experience with hydraulics, I will allow others in the know to elaborate on the Pros and Cons of both systems. Here is a link to "Kenny's Bags vs Juice" page. The prices for both are about the same, but can get outrageous depending on the application. Expect to spend at least $2000 on either system.
