Wow, you were pretty much ignored... That's annoying. Anyways, I agree with you that Aerodactyl should most definitely be praised for it's amazing speed, and being able to set up Stealth Rocks faster then any other Pokemon in OU. I think the reason many shun him over Deoxys-D or even Azelf, is because most people tend to sack their Stealth Rock lead at the beginning of the battle, AKA Suicide Lead. The reason Deoxys-D is used over Aerodactyl as a Suicide Hazard Lead, is pretty obvious because of it's insane bulk, decent speed, and the ability to be slightly offensive and access to Spikes as well. Azelf is used over Aerodactyl because it can use Explosion after getting up rocks, at least that's why I think people would rather use him, and he's got nice SpA too for a final blow with Fire Blast or Psychic. Anyways, Aerodactyl has really nice coverage, so why sack him at the beginning of the battle? If you keep Aero alive for a longer period of time in the battle, he can actually be a really nice offensive presence that can actually fight back against spinners and Steel types. Being so fast even lets him out speed Tornadus-T, and Edgequake is a great combo when facing Sun teams. All in all, Aerodactyl needs some love. Seconding Lavos on moving Aerodactyl to C-Tier.
