Either ratio is going to be better, I think you will have a traction problem either way, if you are not running better tires.
Many do not work to improve the traction after the gear change.
There is some excellent discussion over in the dark side "C6" Some very factual arguments presented. If you are inclined to check some of it out search "tractionmonster"
Here is one link...long read......

I have 4:10's in my 01 Vert, Stroker LS3. Besides the performance improvement with gears, 5th & 6th gears are now very usable.
I'm removing my driveline again, more clutch grief,
if I had any issue with the 4:10's they would be getting changed out as well.

4.10s for sure. I went with 3.90s originally about 8 years ago, just upgraded to 4.10s. It's worth it. You're not gonna have traction either way. Go big or don't waste your money, in my opinion. For a big cammed M6 car 4.10s all the way.

I agree, the small difference between the two is hardly noticeable besides the 100rpm difference cruising. As long as you're not running out of gear for a particular race, I doubt you'd be able to discern a difference between the two imho.
