Why the Wing Zero rules:
It came equipped with the Zero System before the Epyon did [therefore makingWing Zerojust as much a threat to the space colonies as theEpyon (heck, Quatre Raberba Winner actually destroyed a colony under the system's influence )]
It has twin buster rifles (which Quatre used to destroy the colony mentioned above)... Buster rifles are among the coolest weaponry in Gundam Wing
Like the Epyon, Wing Zero also looks cool in bird mode...or should I say, neo-bird mode [it pretty much resembles a falcon in this form (see pic above)]
It's the only Gundam capable of defeating Epyon(which Heero Yuy did against Zechs Merquise in a climactic battle in the last episode (Episode 49)...but Heero only managed to cut off one of Epyon'sarms using Wing Zero)
