Verdict

The call

The clearest difference is review sentiment: ひまわり 全章統合版 at 98% against Celestial Machina's 0%. ひまわり 全章統合版 also leads on ads (none vs shown) and iOS requirement (12.0 vs 16.0). Celestial Machina's advantage is in-app purchases (none vs 1) and update cadence (every 2 weeks vs every 4 months). On price, ratings volume and device support there is nothing between them.
