Today I tried a comparison shave between the PAA Starling V3 OC and the Micromatic Open Comb (MMOC), bumpless version with half spine shim. I had three days growth. I shaved one side with the V3 OC plate and the other side with the MMOC. I did a two pass shave with touch ups in the mustache area. The MMOC was a little more efficient on the XTG passes under the nose than the V3 but the difference as very slight. The MMOC is a little more aggressive than the V3. The V3 provided a more comfortable shave. The end result from both razors was the same level of smoothness. Either would work for 3 days growth.
