OSB, MDF & Chipboard: choosing well

Which flooring?

P5 chipboard flooring is the standard moisture-resistant floor deck. 18 mm is common at 400 mm joist centres and 22 mm at 600 mm centres, but follow the maker's span table.

OSB or plywood?

OSB3 is usually cheaper and fine for most structural decking in humid conditions. Plywood is stiffer, takes fixings near edges better and performs better where it may get wet.
