I'm not really sure about the air force caring more about you, the military is the military. With that being said my friends in the marines were going to Afghanistan for 9 months at a time, the air force was only sending ppl for 4 months at a time to Iraq and feeding you steak and lobster. And it depends a lot on the job you choose. If I could do it all over again I would be a loadmaster, you get to fly around and drop stuff out of the back of the plane or push army paratroopers out. Plus you are aircrew and aircrew gets treated better than anyone in the military.
Air force basic is very, very, mentally stressful. The attention to detail think is no joke, your socks have to be folded a certain way, your laces have be laced a certain way, there is a rule for how to do everything and the training instructor is always waiting for someone to screw up so he can make your entire flight do pushups or flutter kicks. And you march all day long every day or your sitting in a classroom for hours on end dying of sleep deprivation. My friends in the marines had fun in basic training, they mostly exercised and shot guns and did tough guy stuff and then got really crappy anchor and globe tattoos. and remember the recruiters lie their asses off to get you to sign, so double check anything they say with someone who is in the air force.
pro: The air force will pay for 100% of any college you want to do
