JK Rubicon wrangler (stock), is not comparable to ANY suv in terms of off road capability, There is a reason it was voted best 4x4 of the decade. But you'll sacrifice a smooth ride during day to day driving, but if your using it for logging roads and gettin to back lakes it really is basically an over sized ATV.
And yes I have a JK LOL
I do also like the 4runner, and am thinking of getting one for my wife.
Do a search and compare xterras vs jeeps(wrangler). Start with the suspension, drivetrain, add ons ect...
4runner without question will be more reliable than the jeep, but they really are different creatures.
Good luck with your search.

The old X after deer hunting, and yes you could fit a deer in the back with the seats down LOL
