It's great to be an offroad fan with cash to burn. Automakers have been hard at work improving their established 4x4s. Pole position is now held by Lexus with its new GX550. So we took one to Pennsylvania along with a Land Rover Defender and a MercedesBenz G550 to suss out which rockcrawls past the others in this highbrow, highluxury, highprofit wheeling segment.

Which would you take home?
