I working on picking my next 40k army, tyranids and tau seem to stick more to me than the rest of the army's in 40k. I love the mobility and guns in tau, and I like the Large broods of gaunts that overrun everything in tyranids. But I cant seem to come to a decision between the two. $$$ is a factor and im not the best painter in the world, if someone could give me some insight on the subject it would be much appreciated. Thanks in advance.
