I can make this a simple question and answer. Tuono is a perfect streetbike. Comfortable and even fast on the track. The Mille looks more exotic (but gets just as many looks at the coffee shop) AND has a windscreen which I absolutely require on my primary bike. The Tuono easily wins the around town running arrands test and you can easily take it out with your racer buddies.
Here is a first hand account of a Tuono owner mixing it up with his buddies IRL. It's an interesting read:
