JD 1590 drill, 2pt versus dolley wheel

We are looking to upgrade our well worn great Plains no till drill. There is a nice 1590 coming up at an auction. It has the 2pt hitch. Was looking for opinions on the 2pt hitch versus the dolley wheel style. I always thought I would prefer the dolley, but this looks like a nice drill. Any thoughts or experiences?
