Verdict
The clearest difference is price: BlueS at Free against BlueSim's $4.99. BlueS also leads on iOS requirement (13.0 vs 16.4). BlueSim's advantage is update cadence (every 5 days vs every 3 weeks) and chart position (#149 vs unranked). On ads, in-app purchases and device support there is nothing between them.
