Verdict
The clearest difference is rating: Physics Toolbox Sensor Suite at 4.7 against Spectrum Compact Simulator's 1.0. Physics Toolbox Sensor Suite also leads on update cadence (weekly vs every 2 months) and ratings volume (1.8K vs 1). Spectrum Compact Simulator's advantage is in-app purchases (none vs 1) and iOS requirement (7.1 vs 16.0). On price, ads and device support there is nothing between them.
