Disclaimer: I skimmed through the responses, but didn't see these counterpoints:
1. What is your primary use case?
2. What is your current power level and / or desired power level?
For a street car:
Lowest power - 4.10
Medium power - 3.73
Higher power - 3.55
Example:
My car is an Eaton swapped Mach 1, stock bottom end, pretty much every bolt-on except supercharger upgrade and lower pulley swap (still 03 / 04 Cobra crank support). H.P. to the tire is 470 on 10 lbs. boost. I don't recall TQ atm. My rear gear is 3.73, trans is close ratio T56 Magnum (numerically lower 1st & 2nd gear) where the wide ratio has a steeper 1st & 2nd. I run 200 treadwear 315 x 30 x 18's. I could run 100 treadwear / drag radials, but the car is more all purpose than street / drag. Anyway, enough on that mess...
3.73 on my combination is the lowest I should go on my combo based on available traction. On cooler / moderate heat days, 3rd gear skips for traction. More towards winter, it will roll the tires merging onto the interstate in 3rd. A 6 speed is great, but if you spn through half of them, I don't consider that car a well thought out street car.
My aspirations for the car is 650 + on the very low end and likely closer to 800. With that power level, 3.73 will be ice capades.
Long story short, I will switch back to (stock) 3.55's. Gear the car for your power goals.
