I'm happy with my 3.88 RP and stock gears with my turbo motor on the street. I don't normally cruise fast tho, because as RPMs rise the motor gets too hot.
It could easily pull one of the aftermarket 3.44 RP's which would be cool to try out, as I'm not sure how city driving would be with that.
It would be great if someone sold some larger diameter wheels/tires that could be slapped on to test a higher ratio without swapping trans.
