Your question really depends on 2 main things, yourself and your financial circumstances.
Are you confortable with spending large amounts of money to do integrated which includes flying before you have passed the ground exams , find you may not have the aptittude for them and lose all that money on flying?
OATS and BAe offer a a good integrated system which i think a lot of us would do if we had the money. These days it is more likely that even at a lot of the big schools a lot of people are modular.
There are a good ground schools which specialise in that area and flight training FTO's that specialise in theres. I think send clowns has hit the nail on the head, it is with what you are most comfortable, and is it JAA you are going for or an NZ Liscence?
Also if you have the time, difficult as this would be, a personal visit would be well worth your while before making any such decision, i suspect that a lot of people have been stung one way or another during there flight training, ground school, me included.
Have fun, sorry if this has thrown more probs in though
