Verdict
The clearest difference is rating: Whethr at 5.0 against Mercure's 4.0. Whethr also leads on ads (none vs shown) and monetization model (free vs ad-supported). Mercure's advantage is update cadence (monthly vs every 2 months) and ratings volume (5 vs 1). On price and in-app purchases there is nothing between them.
