Yes i do. No chain is stronger than its weakest link and all three diffs use the same flange size (some are coarse and some are fine but dia is the same.) 
Is it reasonable to think that a diff is inferior because of the size of the shaft down stream from the smallest area ? Not really the flange spline is the smallest area and there for the weakest and it is the same for them all. Also many other diffs we consider superior are not a lot thicker and some are thinner.. If I had all three and had to buy gears then I will be honest and say I would use the 489 but if I had a 41 case and a set of gears which is exactly my situatiojn i would use them in a second. and did  32000 miles ago.
