Verdict

The call

The clearest difference is review sentiment: Call Blocker at 78% against Block's 30%. Call Blocker also leads on rating (4.5 vs 4.1) and ratings volume (1.2K vs 18). Block's advantage is update cadence (every 2 weeks vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.
