I'm going to try to give you a reasonable tip in my opinion: go to one of those big schools only if you get accepted in one of their MPL mentored scheme (which will never make you a real pilot IMHO, but this is a different matter). If you don't make it, go to a normal modular school.
But you really have to make a lot of research about the industry and the possible career path you could take and how to make it.
