Verdict
The clearest difference is rating: Geometry!! at 4.5 against Parametric Factorization's 2.9. Geometry!! also leads on review sentiment (67% vs 40%) and ratings volume (56 vs 8). Parametric Factorization's advantage is ads (none vs shown) and update cadence (fortnightly vs every 7 months). On price, in-app purchases, monetization model and device support there is nothing between them.
