I use both the Coopers and the Mickey Thompson STs. When I researched it they were identical in every spec. They both perform the same for me on the street when fresh and I recommend either of them. The Coopers cost less and they have more local suppliers. I was told by my tire guy that Summit is pretty much the only warehouse for the MTs, which is what also keeps the price up a bit. Not sure how true that is, though. I prefer the less busy sidewall of the MTs.
