3/4" means that one can walk on the roof without that vague feeling of being asea.

I have the 5/8 on my roof (code is really the minimum acceptable) and it sinks beneath my feet.

OSB vs. plywood is 6 of one and half a dozen of the other. It just depends on how much one is willing to pay for roofing.
