I would go with SS4W or Popularity Potion.
For me, personally, when I wear Popularity Potion, I feel like I somehow wind up the center of attention or feel like the life of the party. It's entertaining and light and fun. But when I wear SS4W, I feel like Wonder Woman. I feel strong, sexy, centered, and all around dazzling. So Popularity Potion may make Plonk think, "hey, this girl's cool and fun to be around," but SS4W will make *you* think, "I don't give a shit what Plonk thinks, *I'm* amazing."
