Verdict
The clearest difference is rating: NavStaff at 4.5 against MPDX's 2.9. NavStaff also leads on review sentiment (67% vs 29%). MPDX's advantage is update cadence (fortnightly vs every 5 months) and ratings volume (41 vs 8). On price, ads, in-app purchases and monetization model there is nothing between them.
