I've repaired shingled roofs of both kinds of materials. After a leak, the OSB ones were a lot more prone to needing replacement, than plywood and the damage was more extensive. Where weight is a consideration, plywood is about half the weight of wood chips and glue,
and it doesn't eat saw blades either. The plus side of OSB is that the strenght isn't directional, like plywood. Also important to install OSB right side up, especially on a roof.
From personal experience, build a shed out of plywood, give it a coat of paint or stain and it will outlast the OSB version, a couple of times.
