Verdict
The clearest difference is rating: NBack 3D at 5.0 against Better Brain Lite's 3.6. NBack 3D also leads on review sentiment (100% vs 67%). Better Brain Lite's advantage is ads (none vs shown) and ratings volume (5 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.
