Verdict

The call

The clearest difference is rating: B737 MRG at 4.9 against A220 Guide's 2.0. B737 MRG also leads on ads (none vs shown) and ratings volume (299 vs 1). A220 Guide's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (every 2 weeks vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
