Indeed, I wonder too, why so many chose integrated...
I now study airplane technician, and had the chance to begin my JAA ATPL too a few weeks ago. I didn't do it, for such choices i don't listen to my heart but to my mind. Yes I want to become a pilot, and no i'm not going to pay 70k€ and see where I end. Now I will get a decent college degree as airplane technician first, meanwhile I'm going to get my PPL while working in the vacations. From there I can build my time and my licences. I'll have a nice college degree on my CV, can go on the Erasmus exchange and won't have 70k€ debts when I get all my licences.
The way i see it, the integrated ones chose the easy way, they pay, and after 2 years they will get the bill, nothing to worry about while studying.
