Verdict
The clearest difference is in-app purchases: Sensor+Test at none against Phone Diagnostics's 1. Sensor+Test also leads on iOS requirement (8.1 vs 12). Phone Diagnostics's advantage is update cadence (every 2 weeks vs every 12 months). On price, ads and device support there is nothing between them.
