Verdict

The call

The clearest difference is ads: Second Line Calling/Texting at none against Receive SMS's shown. Second Line Calling/Texting also leads on review sentiment (68% vs 40%). Receive SMS's advantage is update cadence (every 3 weeks vs every 2 months) and rating (4.4 vs 4.2). On price, ratings volume, in-app purchases and monetization model there is nothing between them.
