>>16775813Because of normal Aggron's shitty typing, making it difficult to switch in, and the fact it loses its boosts when it switches out, this also isn't a good option.
Rest Talk is really the best build for Mega Aggron, while normal Aggron is better at sweeping due to STAB Head Smash + Rock Head.
Between the two, I'd definitely say normal Aggron is actually more competitively viable, just due to STAB Head Smash + Rock Head. Gen VI's metagame is shaping up to be all about hyper offense, and Rock is a good counter to quite a lot of popular pokemon right now.
