NH 7070 v.s. NH 460 Roll belt

I'm debating on trading my current round baler off on a baler with the roto cut. I am looking at a low bale count used unit. I am wondering if it's worth looking at a roll belt unit or if there is no real difference. I only looking at roto cut units. Any advice is greatly appreciated. Thanks in advance.
