I have experience no with Ultimaker or Cube 3 but I own a cubepro trio, among three other printers. It’s beautiful, solid, easy to set up and use and has some smart features that none of the others do. I show it with pride because of how pretty and important it looks in my office but it’s always off. It’s by far the most expensive and useless decoration printer.
My advice is that you stay away from 3Dsystems. You will be limited by their small color palette and forced to use only their highly overpriced proprietary cartridges. Slicer is horrible, customer service is useless, super expensive to run. And no, I have never ever had a good quality print.
