Verdict
The clearest difference is review sentiment: NORO at 100% against 3D Model Viewer's 59%. NORO also leads on in-app purchases (none vs 5) and ads (none vs shown). 3D Model Viewer's advantage is update cadence (every 3 weeks vs every 66 months). On price and device support there is nothing between them.
