Verdict
The clearest difference is rating: LuckGrib at 4.9 against Marine Weather's 4.4. LuckGrib also leads on ratings volume (338 vs 8) and update cadence (every 2 months vs every 7 months). Marine Weather's advantage is in-app purchases (none vs 6) and iOS requirement (12.0 vs 18.4). On price, ads and device support there is nothing between them.
