Hm, in one direction it's a tie because of how epic the feud was between the Whirlybirdz VHS (Terrence "Twister" Thompson & Wendy Briese) and the "Manifest Destiny" stable...thing.
I put it like that because it was a unit that poked fun at itself-they called themselves a "nation upon itself" to the point where the manager, "Mister Evil", actually bought himself a decomissioned WW-2 Aircraft carrier that he called the "Sovereign nation of Boom-Shaka-Laka".
They did this across five different promotions-it was like watching the Freebirds/Von Erich feud.
