I went 3.73 and am glad I did!
Honestly 3.73's are a little jumpy at times in everyday driving situations. When i put on my summer tires with a 295/45/18 on the rears, my effective gear dropped to about 3.55+ which with my a/t is perfect imo.
Guys with the 4.10 that think its too low migh try a taller tire in the rear to absorb some of the gearing, it helps believe me.
Proper gearing is the balance between power and grip to me.
What's why guys that stay n/a love the 4.10's. At that hp 410's give you the ability to break loose with throttle control...so will the 3.73's with another 150hp as well
Everyone want's to "get to the powerband" faster and get 4.10's.
Well here's my question, don't you want to stay in it longer? Particularly when you are making peak hp??
Gear's get you there quicker, but also get you out quicker as well...something to consider with high power (sc) platforms.
