It's not a straight apples to apples comparison... While DR Diff is great and offers many things he was very forthcoming that the stock axle shafts he sells are made in India. While they are prob ok and some guy's even race with them I decided on the dutchman USA made axles after quite a bit of research. The dutchman axles are around $150 more delivered.
What was the price VS Dr. Diff? More or less than $300?
