Cid Highwind, hands down, because he's the friggin' man!

Cid: "#$#&! Shera, can't you see we have GUESTS?! Make them some %$#! tea!!"
Cloud: "That's okay, we were about to leave anyways....."
Cid: "Shut up! You're gonna sit down in those chairs and drink your G-- D--- TEA!!"

Not only that, he could easily kick as much butt as Cloud in any kind of fights (I'd often take him into the ol' battle arena with the Venus gospel to rack up hideous amounts of battle points).
