Probably depends on what dealers are close to you.
The rental fleets around here use Vermeer and Great Plains. The Vermeer's don't use a coulter wheel so I suspect they will have a tougher time in hard ground, but the one time we used one it worked fine.
Great Plains have a goofy drive disconnect clutch setup that I have to adjust on pretty much every unit we've rented. Otherwise have worked well for us.
I have heard JD's with the 2pt hitch are pretty slick, never ran or been around one so can't really comment.
