Verdict
The clearest difference is in-app purchases: NVS Explorer at none against Physics Toolbox Sensor Suite's 1. NVS Explorer also leads on iOS requirement (12.0 vs 16.0). Physics Toolbox Sensor Suite's advantage is update cadence (weekly vs every 3 months) and rating (4.7 vs 4.3). On price, ads and device support there is nothing between them.
