I voted truggy because they take the most abuse IMO. Monster trucks are durable, but truggies just beat them in every aspect. If you take a revo to the track and a truggy, the trug will last longer and beat the revo by a mile, I've seen it happen, revos aren't tough. Savages are probably the most durable monster trucks, but truggies are a hybrid of the durability of the monster truck and the speed and agility of a buggy. They also have the best parts IMO.
