Verdict
The clearest difference is price: Digital Sensor Wizard at Free against EML Viewer's $1.99. Digital Sensor Wizard also leads on iOS requirement (12.0 vs 17.0). EML Viewer's advantage is update cadence (every 2 months vs every 9 months). On ads, in-app purchases and device support there is nothing between them.
