I have owned a 2210 for nearly 4-years and used a 2320 on the same property for approximately 2-months before switching back to my former 2210. The 2320 has some advantages, namely faster loader, fit/finish with three point position control, nice dash, etc over the 2210. However, my primary interest in a CUT is mowing around my property and I just like the 2210 better, because it responses much closer to a Garden Tractor and I felt the 2320 crossed the line in that you begin to feel more tractor features and less mowing features. This is not to imply the 2320 doesn't mow well, but rather the 2210 feels much more nimble, so IMO there is a trade off and for me, I had to make a decision as to which side the fence I wanted to play. Now, my decision would have been easy to keep the 2320 if I felt the 2210 couldn't perform (loader, tiller, etc.,), but that's simply not the case and smaller cousin does have attitude, so I keep it as opposed to the 2320. However, if I decide to move forward again it will be much further up the chain, so comparing the two will be more "apples to oranges" as compared to two machine back-to-back in the line up.
