Surely a B734 has similar performance no matter which college you choose?
All B734's do not perform identically. It depends on the pilot and the company SOP's.
If you end up needing to know extra aircraft, won't that make you better prepared for operational training?
Any college will prepare you for the examinations. My advice would be to learn as much as you can as early as possible, to prepare you for when the real training starts - at an operational unit.
