Verdict

The call

The clearest difference is in-app purchases: GLB Viewer at none against 3D File Viewer's 1. GLB Viewer also leads on update cadence (every 9 days vs every 5 weeks) and iOS requirement (15.0 vs 17.0). 3D File Viewer's advantage is ads (none vs shown). On price and device support there is nothing between them.
