It's weird. As well as in the other, in this one, the most popular is the one I voted for, and not for being a cool Pokémon or something like that, for my own reasons. For starters, Aerodactyl has a great attack, and Muk has a decent defense. Aerodactyl resists Muk's Poison-type attacks, while Muk doesn't resist Rock- or Flying-type attacks. But Aerodactyl can also learn moves that are supereffective on Muk, like Earthquake (well, in fact the only super effective move Aerodactyl can learn on Poison types is Earthquake).

For my vote, I leave outside the fact that Aerodactyl can Mega Evolve.
