Verdict
The clearest difference is ads: PhoneScan at none against SYSMonitor's shown. PhoneScan also leads on rating (4.0 vs 3.6) and review sentiment (59% vs 40%). SYSMonitor's advantage is update cadence (every 5 months vs every 18 months). On price, in-app purchases, monetization model and device support there is nothing between them.
