Verdict

The call

The clearest difference is in-app purchases: E at none against AL's 1. E also leads on update cadence (every 3 weeks vs every 4 months). AL's advantage is review sentiment (33% vs 25%) and iOS requirement (10.0 vs 14.0). On price, ads and device support there is nothing between them.
