Verdict
The clearest difference is price: BugSim at Free against Evolution's $1.99. BugSim also leads on iOS requirement (12.0 vs 18.0). Evolution's advantage is update cadence (every 8 days vs every 33 months) and review sentiment (100% vs 80%). On ads, in-app purchases and device support there is nothing between them.
