I think Alliance is way better then Horde.
When I first started playing World of Warcraft about 3-4 years ago I started a Tauren Hunter. I was able to get him to about level 26 before I grew bored of him. I decided to try an alliance character. I rolled an alliance human mage and fell in love with the alliance ever since. When I had hit level 60 with my mage I started a dwarf rogue which I used an alliance leveling guide for. I was able to get my rogue to 60 as well and ended up raiding for about the last 3 years on him. It is great to have a rogue by the way.
