Verdict
The clearest difference is rating: Hitee at 5.0 against SunAlly's 3.5. Hitee also leads on review sentiment (100% vs 60%) and iOS requirement (15.0 vs 17.0). SunAlly's advantage is monetization model (freemium vs subscription). On price, ratings volume, update cadence and ads there is nothing between them.
