With the 6.0 you can do about anything you want as it's a nice power plant with a nearly seamless torque curve and broad power band. But my opinion is 4:56's with the OD. That 4L80E has a tall first gear 2:48 and could use a bit over gearing to pull a load from a stop. When playing with an overdrive and 35's I like 4.56's with small block and 4:11's with a big block. Again I find it depends on the motor build though.
