Verdict
The clearest difference is rating: Flash Studio at 4.8 against Horizon Aqua's 3.3. Flash Studio also leads on review sentiment (58% vs 28%) and ratings volume (5.7K vs 3). Horizon Aqua's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, in-app purchases and device support there is nothing between them.
