Verdict
The clearest difference is in-app purchases: Constellations Puzzle at none against Pi's 6. Constellations Puzzle also leads on iOS requirement (13.0 vs 15.0). Pi's advantage is ads (none vs shown) and ratings volume (1.7K vs 21). On price, rating, review sentiment and update cadence there is nothing between them.
