Verdict

The call

The clearest difference is ads: Moore Performance at none against 4iiii's shown. Moore Performance also leads on iOS requirement (9.0.0 vs 15.0). 4iiii's advantage is update cadence (every 3 months vs every 48 months). On price, in-app purchases and device support there is nothing between them.
