I believe an RDS will typically be more rugged than an HWS, simply due to the complexity issue, you can see how an HWS has way more parts involved than an RDS:


That being said, the question of whether or not an HWS is rugged enough is a separate one, and I'd say that yes, a quality HWS is more than duty grade. I would look to switch from an HWS to an RDS based on other considerations rather than raw durability, outside of some extremely niche scenarios.
