Verdict
The clearest difference is price: Good Time Blues Fest at Free against VB3m's $14.99. Good Time Blues Fest also leads on update cadence (every 2 days vs fortnightly). VB3m's advantage is chart position (#177 vs unranked) and iOS requirement (12.0 vs 15.1). On ads, in-app purchases and device support there is nothing between them.
