Verdict
The clearest difference is in-app purchases: Field Technician App at none against Orion Sentry's 2. Field Technician App also leads on iOS requirement (13.0 vs 18.5). Orion Sentry's advantage is update cadence (every 9 days vs every 2 months). On price, ads and device support there is nothing between them.
