Verdict
The clearest difference is rating: USmart Go at 2.7 against Smart Elfin's 1.4. USmart Go also leads on update cadence (every 5 days vs fortnightly). Smart Elfin's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.
