Which military branch is better for me?

I want to be an M.P (Military police..or as the navy would call it Master at arms). But Im not sure which military branch would be better for me! Army, Marines, Air Force, Navy, Coast Guard? Which military branch offers a better more educated well trained M.P position? I qualify for M.P or M.A for every Branch Cause I called and went through all the qual process with every military Branch recruiter. In the long run I want to be a state trooper. So I am only looking to stay in the military for at the most 10 years. I might make a career out of it. depends. But I def want to be a law enforcement officer. I have a bachelors degree from college in criminal justice. will that help out in rank? I know alot of friends in the military. Some of them like it, others hate it. So they don't really help me out at all, lol.
