Stronger: Mavic Cosmos or Open Pro?

Which would be stronger for a rear wheel. Mavic Cosmos or Mavic Open Pro?

195lb rider, 9sp, wheel must be used for all purposes (commuting, racing, training).

It’s the same rim as far as I can tell.

The Open Pro could be stronger, depending on how it is built. The Cosmos is still a pretty durable wheel, though.
