I'm using the older (top) design Overdrive MaxxProtect 700x40 (622-42), and have had them on my ex-commuter/now tourer for a little less than a year with more than 1500 miles on them with 0 flats. They're quite heavy and have more rolling resistance than the previous Michelin Pilot City 700x38 (622-38), but they also handle much better on dry and wet tarmac.

Just don't make the same mistake I did and pair them with Michelin ProtekMax inner tubes which weight a ton! The ProtekMax tube in my front tire finally died after 2000 mile when the Presta valve flange area burst apart causing a blowout. When I changed the inner tube and put in a spare good quality non-sealing tube, I noticed a major difference in the way the Overdrive performed. It feels much lighter and faster, and I also *believe* that the ride is a bit softer too, although it could be my idea.
