I am a current intergrated student at cabair in cranfield. About half way through the ATPL and so far have enjoyed my time here.
Cabair are not perfect, but then who is, but they were right for me and I guess the best advice I can give you without opening the whole intergrated vs modular or OAT vs cabair vs BAE vs whoever can of worms is this :
Decide what you want in an FTO and then set all your options against this wish list, pick the one thats best for you and not what other people would have you think for whatever reason.
At the end of the day you will hear many different people with many different views of what the best option is, but its your money and your time so do whats best for you.
Back to Cabair, I have found the instructors both flight and ground school to be very good, most of the aircraft are working most of the time though the good old british weather can sometimes play havoc with the flying program.
But all in all I have found the place to be pretty good and generally good value for money.
Hope that helps and good luck with whatever you decide.
