Verdict
The clearest difference is ads: EVA 3D™ at none against USB Camera's shown. EVA 3D™ also leads on device support (3 vs 1) and iOS requirement (13.0 vs 17.0). USB Camera's advantage is update cadence (every 10 days vs every 4 weeks). On price and in-app purchases there is nothing between them.
