OSB is not very nice either. Plywood is definitely the choice here.

I think MDF will easily last until his kids don't fit in it though. I don't think he's going to use it in the rain.

Advantech OSB will outlast conventional plywood by a mile in the rain. I exposed it, flat (the worst way possible) as subfloor, to rains for 1+ year while building my house with only maybe 1mm of fiber degrading on the surface a few places. Many modern OSBs use hydrophobic glues impermeable to water.
