Tau are more advanced in some ways and less advanced in others. Taau have hover everything, but the Imperium has guns so big the Tau don't understand how they were made. The Tau have drones, the Imperium has (relatively) safe Warp travel.

The big thing, tho, is that the Tau understand their own technology and can easily replicate it. Which isn't true of the Imperium. The Tau are also very inventive and endlessly iterate on their technology, always striving to improve it. Which, once again, isn't true of the Imperium.

That's the whole thing about the Tau, they have a lot of potential that the Imperium doesn't.
