Verdict
The clearest difference is in-app purchases: Bluetooth Control at none against PolyFill's 3. Bluetooth Control also leads on ads (none vs shown). PolyFill's advantage is update cadence (every 6 months vs every 111 months) and iOS requirement (14.0 vs 26.0). On price and device support there is nothing between them.
