While its true that the lower the number is, the faster you can ultimately go ... the reason why you go with a higher ratio is so that you accelerate quicker. Having a high top speed does you no good if you can't reach it before you run out of pavement.
Remember, these cars have 6 gears and they don't us all of them in the 1/4. A stock SS M6 will top out at about 110 mph in 3rd gear, which is about what they run in the 1/4. If you had a set of 4.10's it would max out at a little more than 90 mph in 3rd. But shift in to 4th and it can now go up to 130 mph.
