I think the H3 brochure is pretty good. Did you get the 49 page brochure?

Basically the Jeep Wrangler 4x4 system is less complex than the H3s.

Anyway I hope this helps..I prefer having control of the vehicle rather than a bunch of sensors doing it for me (think Land Rover)...ABS excluded in emergencies etc.

The H3 uses full time 4x4 where the Wrangler is in two wheel drive until the driver engages 4x4 with a lever.

The fulltime 4x4 transfer case allows for use on the highway ("4 High Open")by allowing the front wheels to rotate separately (diff numer of rotations) from the rear wheels where a part-time transfer case the front and rear wheels are mechanically connected and will create bind on the paved highway and on turns.

I beleive you can lock the T-case ("4 High Lock") on the H3 in 4x4 for off road use (this is different than the rear axle locker)

The H3 transfer case is controlled by a switch on the dash (driver controlled) that activates a solinoid to engage low range rather than a lever (all mechanical) in the Jeep Wrangler.

The rear locker on the H3 with the Adventure package is controlled (driver controlled) by a switch on the dash and for use in low range at slow speeds ("4 Low Lock"). The H3 has a rear locker where as a Rubicon Wrangler has a locker in the front and rear axles.

The H3 uses traction control system (part of the (ABS brakes) to control wheel spin and may simulate a front locker..I haven't driven an H3 in this conditions yet....so I can't say for sure. I wish the H3 did offer a Front Locker Option.. Maybe the after market will??

The Rubicon uses a dash mounted switch and the lockers are powered by a low pressure air pump.

I cant wait to get my H3 and give it a work out!

Let me know when you get your H3 !!
