Hey a manual vs auto thread, I've never seen one of these before, lol.
The A8 is (mechanically) far superior to the M6, facts. It holds up better to mods/power, hell the M6 will fry the clutch after some hard launches on drag radials. I'm not scared of the M6 on the streets or the track. I will out 60ft you, and it's all over from there. Plus I have a Hellcat Redeye, the manual is so lame it doesn't even come in a Redeye, lol. So unless an M6 is heavily modified it doesn't stand a chance. If Dodge would have at least not given it such awful 1-3 gearing it would have been a better option imo. I have driven and owned both M6 and A8. The only argument for the M6 is "fun factor" which is subjective to who considers which one more fun to drive. I prefer the responsiveness of the quick shifting and always in the powerband A8. While you're busy trying not to miss a shift and wheel hoping I'll be long gone. I used to love manuals, but stock autos are now far superior. The manual is dying, buy one if you want one because each year they die just a bit more. I used to love CDs, but now I stream my audio. Technology eventually catches up and replaces out dated things, manuals are one of them.
