In the USA, unlike some industries, in aviation it does not really matter where you go to school or what college degree you earn. experience is what counts the most. I highly recommend that you study something that can provide a good backup career if you need one. Aviation is a very fickle business and there are many reasons why you might need to find employment other than flying. A "professional pilot" type of degree generally cannot employ you outside of flying for a living, and except for a few narrow segments of aviation, such as federal government flying jobs (such as for the BLM or USFS), it will not give you an edge over other pilots who hold a non-aviation degree.
I know. I have one of these degrees. It hasn't helped my career in any way I've been able to determine. It certainly hasn't made me any more competitive in the job market. The airlines in particular do not place any emphasis whatsoever on aviation degrees. What matters to them is that you have some sort of degree and a lot of flying experience. What a degree shows is that you are reasonably intelligent, able to endure a rigorous course of study without giving up, and are probably trainable with a high probability you won't drop out of training (by law, every airline has to put you through an extensive pre-employment training course, regardless of previous experience).
There is also no "best" flying school. The best one for you is not necessarily the best one for somebody else. You would be wise to do some research on choosing a flight school that suits you personally, from price and location, to facilities, equipment, your particular goals and aspirations as a pilot, and you should evaluate the overall personality of the school and instructors by visiting them and seeing if it feels comfortable to you. .

You should beware of the high-profile, heavily advertised flight schools. Not that they're all bad, but they're often the highest priced while providing a mediocre product. Their advertising is meant to get you to sign up and spend your money, not necessarily to inform you of the facts. A lot of people get suckered into joining a flight school based on their glossy advertising without putting any real effort into discovering if it is really the best choice of flight school to attend. Quite often, the local "mom and pop" flight school is the best choice. They all have to train to the same regulations and standards.
One thing is particularly true, and it is that not all flight instructors are good at teaching, or even like to teach. For many, instructing is simply a stepping stone to a better job. You would be well advised to choose a flight school that has highly experienced instructors with a low turnover of the flight instructing staff. The instructors you fly with are actually more important than the particular school you attend.
