Verdict
The clearest difference is review sentiment: Dictionary. at 91% against Thesaurus App's 29%. Dictionary. also leads on price (Free vs $0.99) and rating (4.8 vs 1.0). Thesaurus App's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.
