Verdict

The call

The clearest difference is review sentiment: Blackjack Trainer at 100% against Blackjack 21's 55%. Blackjack Trainer also leads on rating (5.0 vs 4.7). Blackjack 21's advantage is ratings volume (5.7K vs 1) and chart position (#165 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.
