Verdict
The clearest difference is monetization model: DuckChat at freemium against Shadowing Lab's subscription. DuckChat also leads on iOS requirement (13.0 vs 17.0). Shadowing Lab's advantage is update cadence (every 5 days vs every 3 weeks). On price, rating, ratings volume and ads there is nothing between them.
