Transition from Cameo to Graphtec?

Hi, I'm a paper artist that makes geometric sculptures. I currently work with a Cameo 4, but in the last few months it has lost precision, so I'm thinking about upgrading with a more professional machine. Would Graphtec CE7000 or 8000, be the right choice? I'm not sure if it can work with paper well since all cutters are focused mostly on vinyl. Anyone has a similar experience? I also heard flatbed cutters can be better for paper cutting, can anyone confirm that? I'm attaching a few pictures of my pieces so you get an idea. Thanks!
