Verdict
The clearest difference is review sentiment: Nautical Rules at 100% against Waterway Guide's 52%. Nautical Rules also leads on in-app purchases (none vs 43) and rating (5.0 vs 4.7). Waterway Guide's advantage is ratings volume (2.9K vs 12) and chart position (#193 vs unranked). On price, update cadence, ads and device support there is nothing between them.
