Here is an example to answer your question: I went to a university that had a 4 year degree program in aviation. Everyone earned their ratings up to CFII MEI in 2-5 years depending on how hard you had to work. They all have aerobatic training, tailwheel training, and upset recovery training. During my 4 years we watched a lot of examples and read a lot of accident reports about pilots error. Everyone who earned their CFI instructed for 1-3 years depending on how much the regionals were hiring.

The point is: The students where I learned to fly are exposed to a lot more and learn a lot more than a person who completes a program such as Gulfstream, All ATP, etc.. That is a fact without question. Because of this all-inclusive training, the pilots come out more rounded and better prepared to make sound judgement in the cockpit. I would guess they are better pilots as well. There are exceptions to the rule of course.
