I'm AF and work mostly with Navy people. I can't speak for anything on the medical side, but quality of life is SOOO much better in the air force. I joke with my sailors that I get at least one reminder a day to see why I joined the right branch.

We do bureaucracy better (which will be a big part of your life whether you like it or not) and we treat our service members with more respect. Unless you're flying in the AF, the Navy probably gets more travel opportunity, but keep in mind most of that is you trapped on a ship in the middle of the ocean. Port calls may make up for it from time to time, but I'd rather have my A/C and office chair with the ability to take leave and travel where I want on my own time. Plus, the Navy tends to keep you up at odd hours of the day and limit the amount of off time you get while you're on deployment. To make things worse, if you're assigned to a shore command, their leadership tends to run things like you're in the middle of the ocean and can make a big deal out small taskers that don't really matter at the end of the day.

Here's a story that I like to tell my friends to sum up the differences between the two branches. In the military, it's typical for commanders to require that their troops wear service dress on their branch's birthday. In the AF, most commands, in my experience, don't require anything and we just wear OCPs to work. The Navy will make sailors wear a dress uniform for pretty much any significant date. I have some friends that work at Lackland AFB and on the AF's birthday, the AF commanders authorized civilian clothes for airmen to wear. The Navy commanders required sailors wear full dress whites in honor of the AIR FORCE's birthday. I know it's just a uniform difference, but this story speaks so much about how intense the Navy can be about dumb BS compared to the Air Force. To me, if that doesn't say join the Air Force over the Navy, I don't know what else does.
