I only have experience with the SMP (blue). I have two bikes with them on them - the first bike has a bit over 8,000 miles with SMP tires - 700c28s, no flats. The rear tire on this is well worn, with no tread left, but the blue is not really showing through yet.

The second bike has 4,000 miles on it, with 700c25 tires, also no flats. Some noticeable wear on the rear tire, front looks like new.

The one problem with these tires is that they wear so slowly, it is difficult to get a comparative data set.
