I drove both and bought neither, for different reasons. Main reason I nixed the JD was the dealer. Didn't seem to have time for my little purchase. Attitude is everything. From theirs, I vowed I'd never do business there even though the 2210 was my first choice. I also preferred the treddle peddle not because it was more comfortable, but almost because it wasn't. The fact that you have to move your foot differently to go forward and backward made me think it might be safer in on of those uh-oh situations.
The dealer I bought from sold both MF & Kubota. I went with the GC 2300 really 'cuz I liked the fit better, and I preferred (for no real reason) the two cylinders on the FEL. The specs come out slightly better than 2210 or 2230, but those are on paper; don't know that you or I would ever really notice them.
I gotta agree with Hambone. You're not going to go wrong with either tractor (assuming it's well matched to your uses): go with the dealer that feels "right" /forums/images/graemlins/smirk.gif
