Which is better 4wheeler/jeeps

Yea but the small one has metal bumpers and the grand has plastic that hangs down low, plus you cant lift the grand as high as a small one.
No need for a v-8 in a off pavement vehicle, low torque is king with the ability to still pull at 500 rpms, I would look for one with a 4.0 six and a 5-speed.
