Verdict
The clearest difference is rating: OBD JScan at 4.7 against EZ Key Programming's 3.8. OBD JScan also leads on update cadence (every 3 weeks vs every 3 months) and ratings volume (1.3K vs 32). EZ Key Programming's advantage is in-app purchases (none vs 8) and iOS requirement (10.0 vs 13.0). On price, review sentiment, ads and device support there is nothing between them.
