There was acually a comparison done where someone went from 3.0x to 3.73s AND THE DIFFERENCE Was only 2 tenths. A converter will get you from 3 to 5 tenths providing you can hook up!!!

If you only had the money for one iteam I would say 100% go with the convertor. It makes such a big difference that the ring and pinion is of no matter. If if was a M6 then its all in the rear end ratio but with a A4 it's all convertor. A 3.15 rear is fine if you mate it with a good convertor, just ask the people who have tried it, the will tell you that there is very little difference with changing the rear gear.

. And I know how long it will take to swap the gears, I done it before, its around two hours.

10 hours sounds like 
Just a heads up, $500 seems like the going rate for the swap(not including the rear R&R).
