Can anyone attest to why the Schwalbe Kojak is so popular in the 355 size? From what I have read, the Marathon Greenguard (which is also available in the Birdy's size) has much lower rolling resistance, and offers better puncture protection.

Ok, so the tests were done on the 622 versions, but the Kojak gets absolutely slated.
