I'm a former M4 owner and current M2 6MT owner. The only time lag crosses my mind is between shifts - the dethrottling during upshift causes a drop in turbine speed and resulting lag for .2 second or thereabouts. You wouldn't see this in DCT or auto trans. It's fine and reminds me it's a turbocharged car.

Complaining about lag in a modern, high-compression, DI motor is def. a bit of splitting hairs. With a quick shift it's not really noticeable - esp on the racetrack. The M4 has the same characteristic, although slightly less pronounced due to the smaller TT S55 design vs N55
