The call

The clearest difference is rating: OpusTel at 5.0 against swype's 3.8. OpusTel also leads on review sentiment (80% vs 41%) and monetization model (free vs free with in-app purchases). swype's advantage is update cadence (monthly vs every 14 months) and ratings volume (46 vs 6). On price, ads, in-app purchases and iOS requirement there is nothing between them.
