We love these tires. In our testing the things that we really like are...

Tracking - These tire flat hook up and stay on track. They hold a line, even across varied terrain better than any other tires we have tried. 

Predictability - VERY predictable tires allowing you to concentrate on your line and not what the tires might do. 

Traction - We are running the Tractionator X-Cuiruit intermediate tires and love the way they hook up. They do not swap when climbing loose silty / rocky hill climbs and stay put over clay and wet conditions. Simply an amazing tire. 

Longevity - So far they have been lasting very well. We took these tires on because of a suggestion by a fellow rider who pre-runs Baja on these and reported back with amazing traction, VERY long life and puncture resistance. We will report back our findings ion our NW woods conditions but with over 200 miles on them now and very little wear were impressed.
