why a Ford 9"?

DEFINITELY NOT TRYING TO OFFEND ANYONE WHO CHOSE ONE, but what are your reasons for it? the 8 3/4 is much stronger, has bigger everything (except of course, the ring gear diameter, and in the 741 case the pinion diameter). again, not trying to get anyone hot headed, I'm just wondering what made you choose a 9" instead of the tried and true 8 3/4"
