With threshing , seperation and cleaning the 2588 would do the same- if not better. Power , grain tank capacity and feederlift strength the 9760 is better. The 9760 is rated a bigger class combine , but the 2588 would give the deere a tough match.I think it would come down to personal likes/dislikes,dealers,etc. I would take the 2588 ( cheaper to buy and to operate,simpler and best value of money.)
