The clearest difference is price: Blackjack 21 at Free against Pocket Blackjack's $0.99. Blackjack 21 also leads on rating (4.7 vs 4.3) and update cadence (fortnightly vs every 3 months). Pocket Blackjack's advantage is in-app purchases (none vs 10) and iOS requirement (13.0 vs 16.0). On review sentiment, ads, chart position and device support there is nothing between them.
