Verdict
The clearest difference is review sentiment: Hydra at 75% against EarthQuake Map's 17%. Hydra also leads on rating (4.8 vs 2.3) and update cadence (every 3 weeks vs every 17 months). EarthQuake Map's advantage is in-app purchases (none vs 5) and iOS requirement (13.0 vs 16.4). On price, ads and device support there is nothing between them.
