Aggron often get underestimated due to its low sp defense and 4x to fight and ground, but this monster is actually very dangerous. With proper selection of Aggron's ability he can fit into many roles. If you patient enough you can teach head smash thru eggmove, that is recoil free and stab. Aggron is also an unstoppable tank for a lot of types, making even explosion feels nothing. But for me, the greatest point Aggron has is the way he is underestimated. Metal Burst/ Sturdy combo is satisfying, as Aggron would definitely go last and people would always think that they can kill Aggron in one hit. Metal burst itself is a superior counter due to is in dependency to the physical\special split.
