Verdict

The call

The clearest difference is review sentiment: Mile at 82% against Caltrans QuickMap's 29%. Mile also leads on rating (4.7 vs 3.0) and update cadence (monthly vs every 3 months). Caltrans QuickMap's advantage is in-app purchases (none vs 2) and chart position (#144 vs unranked). On price, ads, monetization model and device support there is nothing between them.
