I've run both, pirelli hands down. I'm a track and street guy, on the street IMO (others I ride with have had the same comments as well) the Michelin gets squirmy at steeper lean angles and over pavement markings. I had a very hard time trusting the tires when riding aggressively.
(love the Michelin's on the car oddly enough)
Don't be a road crayon, pavement does not care how cool you think you look in a t-shirt and shorts.
