Verdict

The call

The clearest difference is in-app purchases: CorePendium at none against STAT EM's 2. CorePendium also leads on ratings volume (1.4K vs 6) and update cadence (monthly vs every 3 months). STAT EM's advantage is review sentiment (100% vs 67%) and chart position (#166 vs unranked). On price, rating, ads and device support there is nothing between them.
