I have an 8 3/4 in my 68 AMX Super Pro car and I have different chunks with gears set up that I can swap in easily for a gear change. I would not want to search specifically for the weaker differentials just because I started out with one. As for strength, there was a time when the beefier 8 3/4 was used in fuel dragsters.
