Verdict

The call

The clearest difference is ads: PixVox at none against Open3D's shown. PixVox also leads on rating (5.0 vs 4.8) and monetization model (free vs ad-supported). Open3D's advantage is update cadence (every 2 days vs fortnightly) and ratings volume (24 vs 2). On price, review sentiment and in-app purchases there is nothing between them.
