Verdict
The clearest difference is in-app purchases: Suchi at none against Marine Compass Pro's 3. Suchi also leads on update cadence (every 6 days vs every 3 weeks). Marine Compass Pro's advantage is device support (3 vs 1) and iOS requirement (15.1 vs 17.6). On price and ads there is nothing between them.
