Blaziken has access to Speed Boost and Swords Dance. Don't forget about Brave Bird, Hi Jump Kick, E-Quake and Flare Blitz.
Infernape has access to Iron Fists and the Elemental PAWNCHes. It also can learn Mach Punch, Close Combat, Fake Out. It also can learn Acrobatics and U-Turn.
I would go for Blaziken since it's just so awesome that it is in Ubers o3o
