Verdict
The clearest difference is rating: National Grid at 4.8 against U's 1.8. National Grid also leads on ratings volume (15K vs 11) and review sentiment (25% vs 0%). U's advantage is update cadence (every 3 weeks vs every 6 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.
