Its so funny how wrong most of you are.
First of all, neither side is better at pvp, i got 5 ally pvp toons en 5 horde pvp. Ive played days that alliance was pwning bg and i had days that horde was pwning.
Also don't listen to the other stuff like queues are faster one side because same with bg, i had days that i had instant bg on alliance and days that i had to wait and vice versa.
On the chat on any side you will see people *****in non stop about opposite side how they suck and camp and are lame etc, both side are equal full of those nabs.
So in the end, choose what you find coolest looking and go for it.
