Verdict
The clearest difference is in-app purchases: STm Pedal Control at none against Blue Switch's 1. STm Pedal Control also leads on ads (none vs shown) and iOS requirement (13.0 vs 18.0). Blue Switch's advantage is update cadence (every 3 months vs every 9 months). On price and device support there is nothing between them.
