Verdict

The call

The clearest difference is ratings volume: Water Eject at 6.6K against Sound Wave's 124. Water Eject also leads on review sentiment (20% vs 0%). Sound Wave's advantage is update cadence (every 8 days vs every 5 weeks) and iOS requirement (11.0 vs 17.6). On price, rating, ads and in-app purchases there is nothing between them.
