Small bolt pattern VS. Big bolt pattern

Hey guys,

this may sound like a stupid question, but is there a strength difference between small bolt pattern and big bolt pattern axles? Or is the BBP better because you can fit larger drums? Just wondering since I am trying to find an A body 8-3/4 and I dont really want to spend even more money on it to change to BBP axles if i dont have to or need to.

Thanks8)
