Verdict

The call

The clearest difference is in-app purchases: Engine Performance Booster at none against 傳說小工具's 1. Engine Performance Booster also leads on ads (none vs shown) and iOS requirement (10.0 vs 15.5). 傳說小工具's advantage is update cadence (every 5 weeks vs every 10 months). On price and device support there is nothing between them.
