There is a whole list of expedite carriers on the home page. As mentioned, who is a good fit would be better researched by calling them. Are you using their trailers or your own, will they let you broker your own freight, how are you insured, sign on bonuses, what they pay and don't. It is a whole list of things all the way to how your drivers are qualified. A standard class A driver is much different than someone with endorsements and whether it is a team. You aren't going to get that answer here. Call them specifically with some type of information.
You are essentially looking at the cereal isle in the grocery store and asking which is best, Lucky Charms or Captain Crunch?
