Had both and it depends on what you like. I will say for most parts of the year I preferred my Grasshopper 223/52. The only really dislike about the Hopper was wet grass and sticky weeds would build up under the deck in about 10 min or less in which I would be cussing to myself trying to keep the deck clean enough to cut. I will admit Scag builds a quality mower but they are the most uncomfortable mower I have driven.
Oh BTW, in my opinion the 23 on the Hopper is not enough engine because it circulates and chopps the clippings so much. Demo both.
