I think it is somewhat safe to say all of us would prefer J on a three-class American Flagship Service 767-223 with 50" seat pitch, legrests, decent recline, etc. than a "First Class" on a domestic two class (especially a 757 American Flackship Sewervice" flight,) except for perhaps a 767-323ER. The service is slightly less intense than AFS (no menus, etc.) but the seats are 62" with better recline than the 767-223.
