Verdict
The clearest difference is price: gcc at Free against Four Colours's $1.99. gcc also leads on update cadence (every 7 months vs every 42 months). Four Colours's advantage is rating (5.0 vs 4.0) and iOS requirement (12.0 vs 15.5). On ratings volume, ads, in-app purchases and device support there is nothing between them.
