i bought a 85 sammy with 34's 2 months ago and would not trade it for any 4x4. i also used to own an 86 runner with 33" boggers, the sammy is better on gas, funner in the bush, harder to get stuck, and a HELL of a lot funner in the summer!
my vote an old sammy
I've been 4x4ing in big-ass chevys, in huge dodge pickups, even an 81 toyota corolla(don't ask)...but nothing has ever compared to the fun and trailing you can do and have in a little sami. They're one of the cheapest vehicles to do up, and the easiest to repair(well...sometimes). You'll dish out a good 10 000 for a done up 4runner, and 4000 for a done up sami that goes more places than your 4runner would. If your worried about size get a long wheel base.
