The OR only has a few things that the SE doesn't have.

*Stiffer Bilstein shocks - this only changes the handling slightly. You can get new 20% stiffer Bilstein for the rear for $120.

*Rear Locker - Currently there are no aftermarket lockers for the new X. But the ABLS does a decent job and the SE has that.

*Hill Decent (only with Auto) - I have only used this one and it wasn't because I had to, I just wanted to see what it was like. Nice feature, not needed.

*Hill Assent (only with Auto) - This is something that is kind of neat and you don't turn it on or off. If you are on a steep hill and apply the break and come to a complete stop the breaks will hold a couple of seconds after you left off the pedal so you do not drift. Again, neat, but not needed.

*Rugged Trail tires - Not the greatest tires, but they are a bit better off road than the Long Trail.

*16x7 (6 spoke wheels) - The SE has 17x7.5 (4 spoke wheels)

*More durable seat fabric - The fabric on the OR model is harder and rougher than that of the X, S or SE. It's also more durable.

Think those are all the differences. I think most you can live without or replace on the SE to be just as good or better than what comes with the OR.
