Rich, as you'll no doubt discover, contrary to your post, there is actually a great deal of information available about almost all UK flight schools, and it's all here on Pprune Wannabes! You do need to learn to use the 'search' facility at the top of the page, and you'll need to learn to distill the rubbish from the useful info. Ignore anything that seems too emotional!
The modular vs integrated debate is always in progress, and provokes strong feelings on both sides of the argument. The deciding factor for many people is the budget they have available - you can go the modular route for not much more than half the cost of the integrated schools.
As for who recruits from which schools, Oxford, Cabair and FTE (integrated) and CTC (structured modular - thanks Alex!) would all like you to believe that the airlines recruit only from them, and that - of course - their students are preferred by far over and above anyone else's. Of course, none of that is true. These are all very good schools, but they don't have an exclusive route into employment. As you'll find by reading around these forums, people get into the airlines using every variety of training provider available, so don't be too influenced by the big schools' marketing hype. Determination, motivation, resourcefulness and luck are the main requirements to be successful in getting employed.
