When I played the Rondo Capriccioso and Scherzo No.2 many years ago, they were of comparable difficulty to me. Perhaps the Scherzo was slightly more tricky to play well, but it depends greatly on the speed you wish to play these pieces.Cannot speak for the others Scherzi as I have not played them. I would anticipate the 1st is about the same as the Rondo, with the 3rd & 4th Scherzi being a step up if not more in difficulty.
