Verdict
The clearest difference is in-app purchases: TOSR at none against Blue Switch's 1. TOSR also leads on ads (none vs shown) and review sentiment (50% vs 17%). Blue Switch's advantage is update cadence (every 3 months vs every 64 months). On price and device support there is nothing between them.
