What would you choose and more importantly why?
While I agree Darkblade about there experience, I must bash on you for your comment on the Warp. Indeed I feel writers have put the Tau outside the normal Warp dimension travel. They are more akin to Star Trek I feel, as they have mastered space travel beyond the Warp. Similar to Eldar gateways the Tau don't travel through the "Warp" as we know it from my understanding. Therefore I feel they are more advanced than humanity which is stuck in a Dark Age.Their knowledge of the Warp/Chaos is practically zero and they haven't really seen the nitty gritty of the galaxy so far.
