One thing different that many folks forget to mention is that the tub lip is gone on the newer JK's. (The part of the tub on all previous Jeep bodys that you have to lift your leg over to get in.)
The new JK models are just like a car. No tub lip. The door lower edge is at the same level as the floorboard.
Ladies like this feature so much better. Could be what caused the rise in popularity.
