After a season of driving the A10, and previously only owning manuals, I officially know I made the right choice. The M6 is a blast to drive, the active rev match is insanely fun to mess with and the ability to rev it in traffic etc. is what it's all about

. That said, for speed, the A10 is an animal. At WOT the shifts are quick, smooth, and just rough enough to let you know you ain't in a 'Benz.
My A10 Gripes:
SOMETIMES behaves weirdly for the first <5 miles when cold. (Jerky shifts, searches a bit)
The manual downshifts are not like a DCT or manual. They're rev matched but not aggressively except the 2-1 downshift which got some unwanted attention from a LEO before.
Other than the downshifts and the ability to not rev the car whenever you feel like it, I love the A10. I still have plenty of manual cars.
Can't go wrong with this car. That's the honest truth. Don't get the M6 to go drag racing though.
