In my experience I like the mediums better on soprano. I guess depends on which soprano. Yes, more about feel and tension. The 2nd and 3rd strings are same diameter for both med and hard tension sets. Medium set: 0.019, 0.027, 0.031, 0.022. Hard set: 0.022, 0.027, 0.031, 0.023. The strum bark of the Med set seems warmer to me, and easier responding, but I like a light touch. Overall however quite similar.
