Also depends on if a SC or turbo is in your future. That shorter gear will end up hurting your ET if you go taller than a 3.73. If your staying NA than go for the 4.10, if boosting go with a 3.53 or 3.73 max. I'm also a 2011 auto, chose 3.73. RPMs went from 75mph @ 2,000, to about 2,400. Eat a bit more gas but eff it. I love the response!
