Verdict
The clearest difference is ads: Word Vault at none against Dictionary.'s shown. Word Vault also leads on rating (5.0 vs 4.8) and review sentiment (100% vs 91%). Dictionary.'s advantage is ratings volume (15K vs 4) and iOS requirement (13.0 vs 17.6). On price, update cadence, in-app purchases and monetization model there is nothing between them.
