Horde/Ally, who is better?

[Kutotems]

I always thought that Ally was better when i played 39s pre 3.2 in nightfall with <Hero> still active, but im leveling a shaman at the moment to do more 39s and i cant help but wonder. . . .is it a total steamroll every time for one faction? or is it rather even nowadays in the US?

If tonights games are any indication both sides are quite even.
