Verdict
The clearest difference is in-app purchases: Hutong at none against Equation Loop's 2. Hutong also leads on update cadence (every 9 days vs every 3 weeks). Equation Loop's advantage is device support (3 vs 1) and iOS requirement (15.6 vs 17.6). On price and ads there is nothing between them.
