Verdict
The clearest difference is update cadence: Dolphin at every 2 weeks against NHSA Driver's every 3 months. NHSA Driver's advantage is monetization model (free vs free with in-app purchases) and ratings volume (4.3K vs 1.3K). On price, rating, review sentiment and ads there is nothing between them.
