Should i join the Army or Air Force?

I'm 17 years old, and have a year left of high school. I do not plan on going to college before i join, that's not really an option. I want to join after i graduate and then pursue a higher education. I'm looking to find a job dealing with linguistics, some type of intelligence job. I've talked extensively with an army recruiter and already have alot of paperwork already filled out and whatnot. But I'm being pushed by alot of people to find out even more about the Air Force. I did really well on my ASVAB, and i think i did pretty ok on my DLAB. As of right now I'm looking to make a career out of this. Which should i join and why?? thanks so much!!
