Obviously I have not trained twice so I can't give a direct comparison, but as someone who didn't go to one of the big integrated schools - I think their is a lot of over-hype about the enhanced quality of training at them.
Certainly from some of the guys that went to those schools that I have or do now work with, they often don't have amazing things to say about them. Some had a very positive experience and others not so much. I also know a couple of people who are now instructor at these schools themselves and they have expressed that there were surprised at that (lack of) quality of training compared to the small PPL clubs they taught at previously.
