Verdict
The clearest difference is rating: Chess at 4.5 against SherlockForms's 1.0. Chess also leads on update cadence (every 6 weeks vs every 12 months) and ratings volume (11 vs 1). SherlockForms's advantage is in-app purchases (none vs 1). On price, ads and device support there is nothing between them.
