I do not have enough information on what would be the better mower for your intended use. You are pairing a new tractor against a used tractor in posting. The questions are what is the size of your lot? Does it have slopes that have to be contended with?
Personally I would save the money and go with the Deere, There are several reasons that the Deere is the better, One is a more rigid and robust frame, probably a much better engine and the transaxle is probably a higher grade.
