However, and this might sound contradictory, the BMW's response to the driver's push on the pedal in quicker. Overall response and gear progression make the BMW's a winner, though.
It's not contradictory, you're absolutely right. All manufacturers have a certain lag built into the software for their shift paddles and it varies between them. Mercedes has a very, very long lag for example while BMWs tend to have much less software lag. There are a number of reasons for this, I know on my 335is I'm glad there is a tiny bit of lag because it lets me double or even triple tap the downshift paddle before the shift actually happens, this way I can go straight from 7th to 4th instead of going through each individual gear.

I mentioned Mercedes specifically because I was looking at an early year C63 which had annoyingly laggy paddles and I found out you can get a transmission tune that reduces the lag. Newer year C63s have much more responsive paddles because they were reprogrammed.
