Verdict

The call

The clearest difference is rating: Fly Delta at 4.8 against Allegiant's 2.8. Fly Delta also leads on review sentiment (39% vs 7%) and ratings volume (7M vs 8K). Allegiant's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, update cadence, in-app purchases and iOS requirement there is nothing between them.
