Verdict
The clearest difference is review sentiment: Physics Toolbox Sensor Suite at 80% against µMagnetometer's 23%. Physics Toolbox Sensor Suite also leads on price (Free vs $1.99) and update cadence (weekly vs every 4 months). µMagnetometer's advantage is in-app purchases (none vs 1) and iOS requirement (11.0 vs 16.0). On ads and device support there is nothing between them.
