Hmmmmmm....Let's see....

Rubicon vs. Xterra
Chrysler reliability (HA!) vs. Nissan reliability (meh)
Solid Front Axle (articulate) vs. IFS (just lift the wheel)
Solid Front Axle (hell on the freeway) vs. IFS (Rides like Dad's Camry!)
FR and RR Lockers vs. Optional Rear Locker
Huge aftermarket following vs. limited aftermarket following
Doesn't need mods to hardcore wheel vs. Hello, Calmini!
Convertible vs. Hard Top
Bring a buddy camping vs. bring buddies camping
Gets you there vs. Gets you home

And the winner is............

The Toyota Land Cruiser FZJ80

What.

Toyota Reliability
Solid Front Axle (and still rides like Dad's Camry!)
Front and Rear Lockers
Huge Aftermarket following
Needs few mods to hardcore wheel
Goodbye Calmini, Hello ARB!
Hard Top, but w/massive sunroof
Seats Eight--Bring small tribe camping
Gets you there. Gets you home.

Oh, and a used one with low miles can be found for about half the price of an Xterra or Rubicon.

Sexy, too.
