some people wouldnt be different, but they all have very different personalitys than the juggernaut. he just doesnt care. hes not fighting for some cause, no truth and justice, no world domination, he just does what he wants at the time. i couldnt see someone like galactus turning a doorknob to get into a room, or trying to find a key, or trick someone into opening it for him. hed just walk straight through, or destroy it and walk through what was left of the wall (assuming its a big enough door for him to fit. does that make galactus a moron?
he doesnt randomly smash things either, after he finished smashing colossus with half a building he have wolverine money to pay the owner for damages. after he tore apart a fire truck he donated money to the fire department for having guts, and because he damaged their property. he doesnt just walk around looking for things to smash. he goes where he wants, if somethings in his way, then it gets smashed.
his only powers are to be indestructible, unstoppable and seemingly infinitly strong, when he gets into a fight he doesnt have alot of options other than stand there and hit. no fancy telepathy or flight, he doesnt control the elements. he just hits things, hard. id say having his power and trying to find other solutions, when you can be removed from the battlefield and have no way to get back other than walk, would be a stupid course of action.
straight foward attack is usually no risk to him at all, he gets the job done quicker, and there is less chance someone will come along and hit, or throw him hard enough that he has to spend hours walking back to the same spot. being strong, and using your strength, doesnt make you stupid. its stupid to have strength and not use it.
