I once worked at a school that provided both Integrated and Modular. I worked in "sales", and we pushed the integrated program quite a bit... the reason being that the integrated course was less flying hours but had a higher pricetag since it was supposedly "better training." More expensive but less flying hours... think about that for a minute. The school made a larger profit on integrated students.
Were the integrated students better pilots? No, they received the same instructors, same aircraft, and roughly the same syllabus and used the same examiners and were tested to the same standards...but they were treated a little differently since they paid more.
