Verdict
The clearest difference is rating: GWSCAN at 4.4 against MotoLink's 1.5. GWSCAN also leads on ratings volume (108 vs 2) and review sentiment (68% vs 50%). MotoLink's advantage is update cadence (fortnightly vs every 2 months) and iOS requirement (9.0 vs 13.0). On price, ads, in-app purchases and monetization model there is nothing between them.
