Verdict
The clearest difference is ads: engine at none against StoreCard!'s shown. engine also leads on device support (3 vs 1) and iOS requirement (13.0 vs 17.6). StoreCard!'s advantage is update cadence (every 3 months vs every 13 months). On price and in-app purchases there is nothing between them.
