The 10 speed is more promising in that the torque converter doesn't have to unlock to change gears. If the paddle shifters work properly, then the 10 speed is probably the unit to compare to the PDK.

Incorrect. I'm amazed how often I read this and people get it wrong. GM only said the 8 speed was faster in upshifts under WOT. (and I don't think this was even talking about paddle shifts either...just the transmission shifting)
