What gears do I need?

I have a 2009 Jeep Wrangler X with a Terra flex 4" lift and 37x12.50 tires with the stock 3.21 gears in it. I bought it this way about a month ago and im putting lower gears in it. I need opinions on if I should go with 4.88's or 5.13's. Im looking for a setup for street and off road combo.

IMO, the 4.88s should be fine if you're wanting a compromise for both street and off road.

Plus so I'm told if you have a Dana 30 up front 4.88 is about as big as u would want to go. They say any bigger then that in a dana 30 you start busten gears.
