The delta is really nice and the quality is beautiful both machine/prints. I'm actually checking out the Rostock with the huge build volume... it just looks incredible! How often does the Orion break down and what exactly breaks? I'm definitely considering it just for the price, quality, and it just looks so cool lmao. Not to mention I like the setup for the extruder and hotend. The Ultimaker though is still top bar quality wise. Lots of assessing to do.
