As I'm reflecting on my HC purchase, I would like to say for me the M6 was the way to go. My last car (after the S2K) was a 2007 C6 convertible. I really wanted the manual in that, but settled for a great deal and got the A6. I regretted that decision on the way home and for 6 more years. The A8 in the HC is supposed to be spectacular and I'm sure it's light years ahead of the transmission I had in the vette. That being said, for me, there is nothing that increases the enjoyment of driving than banging the gears myself.... It is clearly a debatable decision as there are numerous threads on the subject. If you like a manual transmission, don't let the reports of the M6 having a tough clutch dissuade you -- they are overblown IMO.
