Verdict
The clearest difference is in-app purchases: ServoMote at none against Antenna Tools's 1. ServoMote also leads on ads (none vs shown) and update cadence (weekly vs every 4 months). Antenna Tools's advantage is iOS requirement (13.0 vs 26.0). On price and device support there is nothing between them.
