Verdict

The call

The clearest difference is rating: Power Thesaurus at 4.8 against Pocket Thesaurus's 4.3. Power Thesaurus also leads on review sentiment (86% vs 58%) and ratings volume (3K vs 512). Pocket Thesaurus's advantage is update cadence (fortnightly vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.
