Verdict
The clearest difference is ads: CoMaps at none against US Maps's shown. CoMaps also leads on ratings volume (136 vs 1) and monetization model (free vs ad-supported). US Maps's advantage is update cadence (every 3 days vs fortnightly) and rating (5.0 vs 4.7). On price, in-app purchases and device support there is nothing between them.
