Verdict
The clearest difference is ads: PLANETS at none against Watermelon's shown. PLANETS also leads on iOS requirement (6.1 vs 12.0). Watermelon's advantage is update cadence (every 2 days vs fortnightly) and ratings volume (3 vs 1). On price, rating, in-app purchases and device support there is nothing between them.
