I have no experience with the old choppers as this was my first year with a 570R. I have the MAV chopper and wow. Chopped extremely fine when dry, I actually took the knives out during the day. When tough it does a great job and spreads more than I needed. I cut 36' and often had straw on the standing crop. I had to adjust it down from full spread, so I think it would spread 40+ when straw is tough. It takes horses to run with the knives in full cut position. The seperate chaff spreaders are great also, they spread heavy material full width. If you want fine cut around3" long, then it will work great for you.
