Verdict
The clearest difference is in-app purchases: Outside Maps at none against MapLayers's 1. Outside Maps also leads on ads (none vs shown) and iOS requirement (12.0 vs 14.0). MapLayers's advantage is update cadence (every 3 weeks vs every 2 months). On price and device support there is nothing between them.
