Self propelled swather vs triple mower mounted units

I'm looking at buying a new mower conditioner for grass hay. I've got a NH 1431 rubber on rubber as well as a JD 946 impeller. Looking to go to a "one tractor" unit. Either a self propelled disk swather (16') or a the type of mower that mounts to front and rear 3 point hitch to make a 30' cut. Looking for opinions on both types as well as what brands you would recommend. I run beef cows and feeder calves. Cut around 500 acres of wheat/ryegrass along with 500-600 acres of fescue/orchard grass.
