Verdict
The clearest difference is rating: Red Book® at 4.8 against Face2Gene's 2.1. Red Book® also leads on chart position (#196 vs unranked) and device support (4 vs 2). Face2Gene's advantage is in-app purchases (none vs 2) and update cadence (every 3 months vs every 11 months). On price, ratings volume, ads and iOS requirement there is nothing between them.
