With the limited choices of ratios for the 8.25 if the optimum gearing for your combo turns out to be between those ratios and it is available for the 8 3/4 then the latter would be the rear assembly to use....I think that any small benefit (if there is one) in performance with the same ratios in each would be overcome by the flexibilty of the 8 3/4.....
