This isn't rocket science is it. It depends very much on our definition of best!
They are 2 of the 4 UK CAA integrated schools.
There is also an Irish integrated school.
There are also plenty of modular schools.
Why are we obsessed with the best?? As an FO of four years now I have mates from both backgrounds. The airline industry has a weight of those of a certain background but thats kinda obvious. That's not to say the other is inferior.
This whole game depends very much on the individual.
