I really like the Pirelli’s.
As a heavier rider who loves belgian cobbles and dirty country roads every type of Continental tire seemed to flat really fast.
Switched to Michelin Pro4 endurance and they were noticeably more durable (the power endurance seems to get cuts a bit quicker than the Pro4’s).
Then tried the Pirelli’s this spring and rode them without a single flat all summer.
I don’t fear short gravel stretches or rocks and potholes anymore!
And no more eyerolls from the group when I flat YET again 
They might not be the tire you want for crits. But I doubt you’ll find a better rolling, durable tire to do century after century on.
