If there wasn't a govener on them the Auto is "faster" (TOP END) because of gearing , For "quicker" in the 1/4, it is a drivers race.
I'm not sure about Auto Cross, you might be able to leave it in one gear the whole time depending on the course.
IMHO

I love my auto trans....I tried out both.....the auto seemed to have more power. Very smooth when gears shift. I live in a small town, and the auto seems to suit my purpose better.

Depends on the driver. I'd bet 9 of 10 drivers would do a faster 1/4 mile in the auto, because shifting well and fast is a bit of a tallent. I drove stick for years and no way could I match my auto, and I'd almost always grind 3rd or misshift into 5th.
Don't know what the power train loss is, and how much different shift points and gearing are but unless your very good and slapping gears, your not going to be able to take advantage of the slight power advantage of the manual.

for the unexperienced driver, an auto is quicker to shift and smoother
an auto however has a torgue converter, which reduces efficiency, resulting in lower gas mileage and slower acceleration.
Theres a reason why race cars use manuals instead of autos, as well as why calssic car buffs prefer a stick.
I did some reading, and came up with the following:
manual:
Advantages
Manual transmissions are typically more efficient than automatic transmissions. This is because manuals generally involve a clutch instead of a torque converter, which can cause significant power losses. This results in both better acceleration and fuel economy.
It is generally easier to build very strong manual transmissions than automatic transmissions. Manual transmissions usually have only one clutch, whereas automatics have many clutch packs.
Manual transmissions normally do not require active cooling, because not much power is dissipated as heat through the transmission.
A driver has more direct control over the state of the transmission with a manual than an automatic.
Manual transmissions are typically cheaper to build than automatic transmissions.
Manual transmissions generally require less maintenance than automatic transmissions.
In addition, many people feel that driving a manual forces the driver to pay more attention to the road and to other cars, making it more difficult to become distracted.
Disadvantages
Manual transmissions require more driver interaction than automatic transmissions.
A driver may inadvertently shift into the wrong gear with a manual transmission, potentially causing damage to the engine and transmission as well as compromising safety.
Manual transmissions are more difficult to learn to drive as one needs to develop a feel for properly engaging the clutch.
The smooth and quick shifts of an automatic transmission are not guaranteed when operating a manual transmission.
Manual transmissions require more controls than automatic transmissions. This is an issue in cramped cockpits, cars where a floor-shifter is inconvenient, or in vehicles equipped for disabled drivers.
Manual transmissions make it especially challenging to start when stopped upward on a hill, especially for newer drivers.
