1. Great Tires
I've had the opportunity to run these tires back to back on a track (LVMS) againt Pirelli Supercorsa Trackday SC3s. Both tires are excellent and grip well. When I turned traction control off the Michelin's performed better. With TC off the Pirelli's gave me little to no warning they were going to break free when I was hard on the gas coming out a corner. The Michelins were more predictable and would allow me to slide the back end. The Michelin's also seemed to wear better and did not show signs of extensive head cycling. My personal feel is that you can't go wrong with either tire since both are excellent. My lap times were better on the Michelins though. STG is awesome to deal with, My tires arrived in 2 day and were nice and fresh, unlike some places I've bought from where tires show up old and dusty.
