Verdict
The clearest difference is update cadence: EOD at every 2 days against Building a Second Brain's every 4 months. EOD also leads on rating (5.0 vs 4.7). Building a Second Brain's advantage is ratings volume (12 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
