I not convinced the Movos perform any better, but I don't think a good wind noise reduction comparison has really been made. They cost less, look cool, can be shorter and are the new alternate option for folks who want to try something different. I see those things as the drivers for folks using them more than any increased performance difference (which I remain skeptical of).
The acoustic effect of the large diameter rubber cuff in back still concerns me somewhat. How much does that matter? Dunno. Probably depends on the microphone, orientation and and application. The Big Shures are essentially uniform across over all angles of incidence. They are backed up by measurements and Shure's acoustic engineering expertise. Keep in mind that in a vertical orientation, that big rubber Movo cuff with a lip around the edge will no longer be located back in the cardioid null region of the pickup pattern, but will extend out in front of the capsule somewhat at the bottom. Again, not sure what impact that might have or not.
