I'd like to see some empirical proof of any of those three points.
It seems to be obvious if viewed objectively. The revolver design is less technologically advanced. Which one is faster and easier to reload? Which one is lighter? Which one balances in the hand more ergonomically? Which uses more advanced materials? Which has a simpler method of operation (I'll give you a hint, it's not a revolver despite perceptions to the contrary). Listen, I love revolvers, muzzle loaders, crossbows, and atlatls, but it shouldn't require a dissertation of empirical data to recognize the hierarchy.
