Verdict
The clearest difference is ads: Rizzference at none against Acronyms and Abbreviations's shown. Rizzference also leads on rating (5.0 vs 4.6) and update cadence (every 3 months vs every 17 months). Acronyms and Abbreviations's advantage is ratings volume (307 vs 3) and device support (3 vs 1). On price, in-app purchases and monetization model there is nothing between them.
