I don't think you will be happy with any fused filament printer regardless of the make. And, as far as the printed samples on the XYZ site, I think they deserve credit for being pretty accurate representations of the kind of quality that comes off ANY 3d printer of this type. I've seen lots of impressive PICTURES of 3d printed objects, but I've never seen or held one that looks appreciably better than what comes off a DaVinci.
I don't think any 3d FFM printer would get high marks for quality... and no object is going to hold up to any kind of closeup or close scrutiny. Accuracy (and repeatability) get high marks, but as soon as you get into sanding or acetone baths accuracy goes out the window. As for time, even the most modest object can take hours and hours to print, and if you tune up the output for high resolution in order to improve quality you can double and quadruple the time waiting for the object to finish printing.
That having been said, I don't think you can do better than the DaVinci. For the two months I have had mine (with it printing close to 24 hrs a day), I've been really impressed with its ruggedness and reliability. The two downsides to the machine (proprietary filament cartridges and closed firmware) are both easily overcome with aftermarket and open source alternatives.
Ironically, I don't think you can make an informed decision about buying a 3d printer until you've bought a 3d printer. There are just too many factors to consider. For example, the problematic nature of overhangs and designing around that often onerous limitation. That being the case, I recommend the DaVinci printer again, because even if your experience with it leads you to conclude you can do better with some other equipment, you've only spent $500 to find that out, and if your time is worth anything, $500 is not much at all.
Best of luck!
