As
edymonster has said, there is loads of information here on those and many other schools. If you read the
Archive sticky at the top of the forum, you'll find the most important threads about them.
However, 'which is better' is a very difficult question to answer, especially for current students who, almost by definition, only have experience of one school. They are simply not in a position to make any kind of objective judgement.
All of the major schools are good at what they do. They employ good instructors, aircraft, engineers, etc, and will get you through the modular or integrated course that you buy - as long as you put the work in. However, they all have a different style and atmosphere, and it is this that you need to go and look at for yourself. Some schools are quite regimented, others a little more laid back. Some are very glossy, but the glossy approach may not suit you. Some are large, others small, and the way they work may be very different. Go and look at the schools you are interested in, talk to students and staff, find out about how the place works, what the 'feel' is like, whether people enjoy or endure their courses.
Any of these schools will provide you with the tools to achieve the qualification you want. It's how they do it that will determine whether you've chosen the right school for you.
