Both route produce quality pilots but...
This is taken from and interview of one BGS student who I think shows exactly what produce the modular route:
I would always choose the modular route. I believe it forms a more adaptable, self-reliant and well-rounded pilot. Often, integrated training, though of high quality, is too standardised and fails to expose pilots to enough scenarios which require them to problem-solve independently, especially during their hour building.

Monarch, Flybe etc are being aware that young integrated pilots in their 20s are in a rush for flying a wide body in a major airlines! Modulars tend to stay longer perhaps because their are happy enough flying a Saab340 or a Q400!
Good luck!
