Surely the answer is to talk to, or even visit, both of them, and go to whichever you're most comfortable with? Each school must offer a different environment, different instructors, and so on. If you're not comfortable with your training environment, you won't learn so well. As far as airlines are concerned, I'm sure that they would rather employ you if you've come from a school where you were able to perform at your best.
