Question 3.90's or 4.10's for m6?

Is there a big difference between 3.90 gears and 4.10's? I'm trying to decide on which to get for my m6, and noticed that 3.90's are now available for the stock 10 bolt. What do you guys think? Would I feel much of a difference between the two in acceleration? What about gas mileage?

Are you sure about the 3.90's? I know that they are available for Vettes but I thought I had read that 3.90's won't fit the 10 bolt.

Doesn't really matter. Go with the 4.10s.

Had 4.10's did not like them, my choice for you would be the 3.90's, hope someone sets them up right for you.
