Verdict

The call

The clearest difference is rating: Greysheet at 4.7 against NGC's 2.1. Greysheet also leads on review sentiment (38% vs 6%) and update cadence (every 9 days vs every 2 months). NGC's advantage is in-app purchases (none vs 12). On price, ads, device support and iOS requirement there is nothing between them.
