I have about 5K on my rear tire. It's not got much left in it. In comparison, I got 10K out of the OEM Metz. Looks like my riding style has changed a bit.
I like the Strada. Going to put on an Avon next, though, just because it's in inventory. Then I can compare for myself. If I smoke through the Avon as fast as the Pirelli, I'll probably go back to the Strada. Cheaper and easier to balance.
