ATP in my opinion is the best. Yeah, you fly your butt off and it is fast paced. From what I hear you eat, sleep, shower, socialize with any and everything that has to do with flying. It is 24/7. Your day starts out at 6am and ends about 7 or 8pm. True,that's a long day. However, I believe the more often you are exposed to something whether flying or whatever, the better you will be at whatever is you're trying to accomplish. JMO.
