Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello, I am fairly new to the server and I had a question pertaining to raiding guilds, specifically are the more prgressed/accomplished guild on either alliance or horde? I'm not sure if there is any data to back this question up. However I was just curious, seems the horde to alliance ratio is fairly even. Thanks in advance

There are good guilds on each side. Take the red pill or the blue pill.

Generally people who favour PvE roll alliance and those who favour PvP roll horde because of racials. But you should really not base your choice on this, as the above poster said you'll find all sorts of guilds and people on both sides.
