Verdict
The clearest difference is in-app purchases: Openings Mastermind at none against Chess Mega Bundle's 1. Openings Mastermind also leads on ads (none vs shown) and update cadence (fortnightly vs every 7 months). Chess Mega Bundle's advantage is rating (4.6 vs 4.3) and ratings volume (125 vs 6). On price, review sentiment and device support there is nothing between them.
