Verdict
The clearest difference is in-app purchases: Gains Chat at none against H2O's 6. Gains Chat also leads on rating (5.0 vs 4.5) and iOS requirement (15.1 vs 26.0). H2O's advantage is ratings volume (175 vs 6). On price, ads, monetization model and device support there is nothing between them.
