Welcome and congrats! As for your question...well, the OR edition has those handy dandy full skids...and the rear locker...but otherwise...I've seen SEs do everything an off road edition can do. Snow will be determined by what kind of tires you put on it to handle the snow...BFG ATs are excellent for pretty much everything nature can toss your way. Off roading is pretty much the same with your tires...if you want a good all around off road tire, then the BFG AT is good, as well as the Bridgestone Dueller REVO AT...unless you're totally in the mud all the time when off roading, I'd stay away from MTs as I've learned...they have shite for tread wear and you'll go through them quicker.

Good luck with your new X!
