I'll try and keep this as unbiased and accurate as possible from Jeep perspective. It doesn't matter...no "I beat a jeep on this terrain." "Jeeps are just plain better..." IT's a balance, it's not just the vehicle, it's the driver. I wouldn't stack a Wrangler against a X firstoff... it's not even in the same league...they service two totally different consumers, I don't hold any weakness's against my buddies X when he gets stuck...cause I don't have Air conditioning. As for Cherokees and X's, it is a closer comparison but still they end after four doors and storage space...the drivetrain is totally different. How do you decide which sixze is better?? the smaller cherokke or the X??? depends what you need. However the Liberty is a piece of trash...seriously on my jeep boards, out of all the KJ's I see (liberty model name) There is one I respect and it's lifted and looking into a SFA conversion. Seriously, Liberties aren't marketed to the same crowd as the Cherokees and Wranglers, Just as the X isn't. The liberty is more SUV then Jeep. That may sound ignorant but you have to see the culture that has grown from jeeps...the cherokee alone is 20 some years old...the family line goes back atleast 50. That said, I would liek to go back to my previous statement about balance...I wouldn't dare put a cherokee or Wrangler against the X if say the X was driven by an ARCA competitor. It's not just the vehicle you drive but the elements around it which make it great.
