I didn't care for it. I met plenty of great people, some of whom I still keep in touch with, but that will happen no matter where you go as long as your outlook is in the right frame of mind.
I wouldn't do it again, but I did get the GI Bill out of it, and that's making college a breeze. Unlike most of the people in my classes around me, I don't have to worry about keeping my hours at my job ON TOP OF getting my study hours in on my assignments. However, I've become slightly lazy on that type of stuff anyways.
To me, the AF focused too much on your appearance instead of making sure your job performance and technical ability to really show who you were and how you mattered to them.
For example, my last job while serving was a trailer maintenance (MHU-141, 110, and 226) as well as trailer towing (MHU-204 was fun!) with live munitions, but many people instead chose to hark on the fact that I still wore BDU's instead of switching over to the ABU's. I also kept my hair near the longest allowable limits, rather than keeping it right next to skin length. I also grew tiresome of the increased focus on procedural methods from the books, rather than applying "tricks of the trade" and helpful knowledge to all of our day to day routines.
There is no more detailed way to beat a dead horse than what you'll find in an Air Force Technical Order (AFTO).
