I must say zerg... since there's not much that can defend against a drop of 24 full overlords- 12 full with fully upgraded (speed attack and movement) zerglings, the other 12 full of upgraded hydralisks. Even psi storm will only take out a smattering, and there's not much that can do wide enough damage to take out that much force. Zerg may be weak compared to other races, but they have much more strength in numbers- and just like AMD- have a darn good price to performance ratio
