Rubicons have Dana 44's front and rear and 4:10 gears. Non-Rubicons have a 44 in the rear and a 30 in the front, not 4:10s.
All of your other info is spot on but the gear ratios are not entirely correct. Rubicons with the auto now come with 3.73 gears stock. I don't know how many years that they've been doing that but be sure you know what you're buying. 4.10's are a $200 option on the auto, but come standard with the six speed in the Rubicon only. A non Rubicon for 13 will have a 3.21 or 3.73 gear ratio. A good indicator for 3.73's in a non-Rubi is the factory tow package. Many of the plain janes with tow packages have 3.73's.
FWIW, I don't fully understand why anyone with expedition travel in mind would buy a new Jeep that wasn't a Rubicon package. Granted, all of the models are very capable off road, but if you plan to lift or lock a Jeep then it's much cheaper to buy it that way in the first place. You can buy a factory Rubicon front axle for your JK after the fact, but it'll cost you almost as much as the whole package at the lot. Not that I'm being a Jeep snob. I like them all, it's just a better financial decision if that's where you're headed anyway. The Rubicon also has some convenience add ons like auto headlights, power doors, keyless entry, hill descent control, etc.. You get a lot for the money!
