I'm one of the few dudes around who's been both an Academy and ROTC cadet. Honestly, I really don't know which is better. Some food for thought:
1. Do you want to be a pilot? I found that the USAFA system helps you get there much easier. Any medical issues you may have will be solved much easier at USAFA than in ROTC
2. How much do you value the typical American college experience? Rush, parties, late night trips to who knows where, and having a beer and macaroni breakfast are all things you'll never experience at the Zoo.
3. What do you want to do with your summers? USAFA has some awesome summer programs...none of which pay you any more than what you already get paid. ROTC will only steal 4 weeks of your junior summer. All the rest you can work, take classes, or be lazy.
4. Girls. Yes, its possible to date at the Zoo. However, she can't stay in your room.
5. How rebelious are you? You're a member of the Air Force when you're at the Zoo. Too many stupid acts may get you wearing stripes and working in the fuels depot.
