Which one makes a more durable wheel? Sapim Race (double-butted 2.0mm, 1.8mm, 2.0mm) or Sapim Strong (single butted, 2.3mm elbow, 2.0mm rest)?

I've read enough from the the experts here to believe triple butted spokes makes the most durable wheel, but that's not available from the builder I'm looking at.

Sapim suggests it's Strong (single butted) spoke is their strongest ("The Strong is developed for specific and heavy usage such as tandem, e-bikes or heavy load use.")

Does this make sense to the wheel building experts here?
