Ok I see what you're trying to do. You need to compare through theoretical shift points. Comparing gearing only isn't going to show what you'd need to show. Then, you'd need to account for a bunch of other variables.That the automatic (even with the engine output reduced to simulate additional drivetrain loss), puts more force to the ground than the manual for the majority of speeds. More force transmitted to the ground should equal greater acceleration (not accounting for weight, shift times, clutch dumping, torque converter flashing, etc.). It's gearing vs. gearing, multiplied by the engine torque.
I'll take the (limited) mag tests and person experience...
Of course, drive what you like. Subjective experience kind of trumps everything else on these kinds of purchases.
