Verdict
The clearest difference is rating: System Activity Monitors at 4.2 against DataMeter's 3.7. System Activity Monitors also leads on ads (none vs shown) and review sentiment (76% vs 47%). DataMeter's advantage is update cadence (monthly vs every 3 months) and iOS requirement (9.0 vs 13.0). On price, in-app purchases, monetization model and device support there is nothing between them.
