I don't think that is what most people are saying. What I like about ST tires is the fact that they actually provide MORE grip in many real world riding scenarios. Cold, wet conditions? ST tires are better. Sport tires are not sticky unless you get enough heat into them, which is not always easy or safe to do on the street.
Totally agree on the wet condition argument. But I think the 'you can't get enough heat into them on the street' is largely BS. Not only can you flex the tire enough in sport riding situation around here to get heat in them, they don't have to get fully up to temp to offer more dry grip than the average ST tire. A dead cold set of SC2s or SPs has more dry grip than a warm set of PR3s, based on my personal experience with both.
If a DOT race tire offers no grip cold, how come I can put a fresh unscrubbed set on my bike, ride onto the track and first lap out ride harder than I would ever on the street? I'm obviously not up to full pace on that out lap, but I'm pushing it at least as hard or harder than I would on the street, getting to full lean angles and the tire sticks like glue.
