Is it better to enlist in the military or go to a military academy?

So, after looking at becoming a criminal psychologist, I learned that I have to go through almost 10 years of schooling before I can even be eligible to take the test to get certified (this would be me taking the recommended route and getting a doctorate). I also would have no way to pay for it, and although I will look into grants and etc, I’ve been looking at joining the military. I don’t want to join just for free college or what have you, I actually want to serve. I want to become a pilot in the Air Force but I don’t know how to get to that place. I’m not sure if enlisting would be better or if I should try to get into the academy, and then enlist if I don’t get accepted. I also don’t know If I should be the reserves or active duty.
This whole financial issue has really thrown off my goals and I am kind of lost.
