The clearest difference is in-app purchases: Visual Protractor at none against Protractor+'s 1. Visual Protractor also leads on iOS requirement (14.0 vs 17.6). Protractor+'s advantage is update cadence (every 2 months vs every 5 months). On price, ads and device support there is nothing between them.
