Verdict
The clearest difference is review sentiment: TOP at 100% against iPerf's 42%. TOP also leads on rating (5.0 vs 4.2) and update cadence (every 2 weeks vs every 9 months). iPerf's advantage is ratings volume (19 vs 1). On ads, in-app purchases and device support there is nothing between them.
