Verdict
The clearest difference is rating: Greysheet at 4.7 against C's 4.1. Greysheet also leads on review sentiment (38% vs 0%) and update cadence (every 9 days vs every 4 months). C's advantage is in-app purchases (none vs 12). On price, ads, device support and iOS requirement there is nothing between them.
