I agree that the Imperium would win. The Tau doesn't have the numbers to beat them which is why they are only in a small section of space in 40K.

The Imperium is more numerous than any other force listed. They have literally billions of soldiers to waste. And they have the Space Marines, the Grey Knights and Inquistion, members of all these units are easily worth at least a hundred normal men. Seriously read all the enhancements a Space Marine has: they can survive in vacuum temporarily, eat rocks if need be, breathe in even sulphur atmospheres, spit acid, go without sleep for weeks and crush skulls with their bare hands. and their standard issue gun fires depleted uranium shells that explode inside their targets.
