Verdict
The clearest difference is review sentiment: Ocean Watch at 74% against Water Temperatures's 21%. Ocean Watch also leads on rating (4.8 vs 2.5) and in-app purchases (none vs 3). Water Temperatures's advantage is update cadence (every 2 months vs every 9 months) and iOS requirement (16 vs 26.0). On price and device support there is nothing between them.
