Verdict
The clearest difference is in-app purchases: Calculator 4U at none against Grid Calculator.'s 2. Calculator 4U also leads on update cadence (every 3 weeks vs every 5 months). Grid Calculator.'s advantage is iOS requirement (16.0 vs 18.2). On price, ads and device support there is nothing between them.
