Unfortunately it is more a case of the individual trainee and the individual instructor, rather than any particular flying school.
My experience in assessing and recruiting low time pilots to a GA operation corroborates this.
I honestly believe that the two schools to which HJ alludes rely on their reputation a bit - and that doesn't necessarily make it so, a bit of a self fulfilling prophecy really.
IMHO, find an instructor that you feel comfortable with and confident in, and shop widely for this. Don't be sucked in to believing reputations and adverts. Go and speak to people face to face.
