It would be unusual for a student to attempt to analyze the curriculum details behind a type rating.
What you really need to know, is will the employer you are interested in accept a type rating issued by the FAA?
Most nations and international companies will accept either JAA, FAA or both.
Nations which do not directly accept FAA or JAA will normally allow a fairly easy conversion from one or the other, or both.
JAA academic standards are more stringent, so the FAA ratings are usually less expensive, especially if you come to the US.
Also, if you are looking for inexpensive type ratings in the US, the ground training will be mostly self-study, before you attend sim, and will not meet that 72 hour requirement.
There is no written for a type, the oral is usually 2-4 hours and would focus on systems and operating procedures. You would not expect regulatory questions if you are not getting an FAA pilot rating (ie ATP).
As for real-airplane training, if the sim is certified properly, no airplane check is required to issue the type rating. A US employer would most likely have to give you a few landings in a real airplane without pax if you're the PIC. An SIC might not need the bounces but that depends on the company OPSPEC.
