Well it all depends Super Gengar Man.If u use a Snorunt in a Cool Contest and it's Cool Stat is all maxed out and it has a Cool Contest moves it will do better than a Glalie with all Maxed out Smart Stat and it has all Smart Contest moves entering the Cool Contest.
First, the audience preliminarily votes on which four competing
Pokémon looks the coolest, most beautiful, cutest, smartest, or
toughest, depending on what category the Contest is in. Attributes
that the audience likes and the Pokémon's overall luster also
beneficially influences the audience. To make a Pokémon look cooler,
etc., a Coordinator prepares Pokéblocks of a specific color from
certain Berries, depending which category he or she wants to augment,
and feeds them to his or her Pokémon. How well a Pokémon does in this
phase is shown by the number of hearts that appear over the audience
members' heads.-Bulbapedia
