I wonder which is faster...if both have the same rear-end and the same RWHP & RWTQ? In stock form, the MN6 with the 3.42 has the rear gear advantage, the MN6 tranny also is less parasitic. If you bring the two cars to an equal playing field where the only difference is the transmission. I never understood why the 3.42 rear was not used for the A4 Performance Pkg.
the 3.42 does NOT have the gear advantage from the dead stop if you take into account the first gear ratio of the auto (3.15 only) and the stick. The rear end plus the first gear number in an auto is higher numerically (lower geared) than the stick. Check it out, that is what my Helm's manual shows.
A fighter jet pilot doesn't need to be shifting gears, and neither do I. I would love to hand any 6 speed vette there a$$ on a track in the North Alabama area while sipping a drink that I pulled from the CUPHOLDER in my a4 pewter convertible.
Auto's are more fun by far.
Last i checked, this was a discussion about STOCK. If you're stock then you need to put the crack pipe down. Otherwise, I'm sure there's a modded 6 speed that would love to prove you wrong.

lower gearing is usually an advantage in drag racing

A fighter pilot has a ton more stuff to worry about then shifting gears, such as a 3rd dimension, both feet on the rudder pedals, one hand on the cyclic and one hand on the throttle. In an auto you have hands on the steering wheel, one foot working gas and brake, two dimensions, and no control over your transmission, BORING. Sticks are way more engaging and way more fun. So you can kick my a$$ while sipping your drink, but I am still going to have a huge grin on my face listening to my LS1 downshifting.

My point is that if you put a 3.42 in an A4, then the time to run the 1/4 goes down. The car 'as built' favors the MN6 for several reasons; what I am suggesting is to remove all variables other than the transmission.

Great addition to an open discussion.
engines completely stock stanghole, the point was, I'm putting my vote in on the automatic for winning the drag race. I raced a six speed at the local 1/8th mile when I was bone stock, and won, because of a good holeshot, and my lightly modded vette has recently ran another lightly modded 6 speed and won again. Auto=consistency.

FYI, my auto downshifts nicely when I push the gear selector down.
Any decent 6spd driver should be able to make it down the track without missing a gear.
Thank you go proving my point again.
If you evaluate GM test results you will see that .20 sec of the .25 difference comes in the 0-60 mph times. This is because the M6 has a 3:42 rearend NOT because the M6 is a faster tranny. Also this is exactly where the skill of the driver comes into play.
FYI put the 3:42 in the A4 and the .25 difference M6 edge is erased
You can lose 1/4 sec without missing a shift. You can spin the tires off the line, you can shift at too low RPM, you can shift too late and hit the rev limiter. So YES it does come down to the skill of M6 the driver.
So maybe we call it a draw 50/50 because of the variable skill of the drivers involved.
Exactly, that's the point. The tranny is the least important aspect of the car...the HP, the TQ, the tires, the brakes, the suspension, the driver are all significantly more important than the tranny.

Auto's are more fun by far.
A fighter pilot doesn't need a stick, but how many of them do you think drive autos? Very few. Most will go for the stick everytime when they get a fast car(or motorcycle for that matter). Autos are more fun if you're not wanting to be more engaged with what you're doing behind the wheel. They allow you more freedom of movement and where your attention goes, and requires far less from you. Not very engaging to me. But I'm not going to knock Auto owners. Just don't make them out to be something they're not.
I do believe swapping rear gears actually robs measured RWHP, on the dyno.
We lost ~8-10 RWHP when we switched to a 3.42 rear. Acceleration improved significantly; however, we lost some pull above 135 MPH. In the straights at Road Atlanta, I come out of the corner so fast and put so much distance (so quickly) on the car that I pass, that I run faster than when I ran the 3.15 rear.
I enjoy and prefer driving any car with a manual transmission. Always did and probably always will. It's a matter of preference for me.
As far differential ratios you must also consider the transmission ratios as well. Stock for stock the auto with 3.15's has the advantage over the 6 spd M6 with 3.42's, but not the Z06 M12 with 3.42's if they both had the LS6 engine.
I don't care about a tenth of a second. It's about the driving experience, rowing through the gears, downshifting and hearing the engine and exhaust. That's what I like, plain and simple and it has nothing to do with which transmission is better.
I have an A4, and when I ordered my Corvette new, I had exactly NO ONE's opinion in mind but myself. I've had the pleasure of waving goodbye to numerous cocky M6's. Just remember, in the end, when all the talk is over. The one who's the Big Dog is the one who crosses the finish line first, not the one who barks the loudest at the bar. It's a combination of mods that makes the car, not the trans alone.

This whole debate actually becomes somewhat silly. As you said, it's a matter of preference. I just wish that those MN6ers, who are so condescending to A4 drivers, would realize that we enjoy our cars and many times we have faster cars and better handling cars than they do. BTW some of us A4 drivers actually shift too.
