Is the Tau Empire the best Warhammer 40000 army?

"No, because they are robots. If you are thinking of collecting a army, get the Blood Angles"

This is false. Tau are not robots, they just use a lot of robotic war gear. They are a good army to play, as they have been fairly recently updated compared to some other armies (Necrons, Witch Hunters). Blood Angels have also been updated fairly recently, so they are also a good army to play.
