A 4:1 gearbox is like being in the lowest gear on a mountain bike (ie your pealing fast and not going very far, but you can make it up a very steep hill). A 2.56:1 gearbox is like being in a low to middle gear (ie your peading slower, and can't make it up a steep hill, you just dont have the power, so you switch to an easier gear). Same with a lower t case ratio. The 4:1 can crawl and climb better that a 2.56 box. That is why the h3 adventure has plent of power to climb steep ass hills without stalling, even though it has a relatively small motor.
