Verdict
The clearest difference is review sentiment: TopHap Explorer at 77% against Multi's 33%. TopHap Explorer also leads on rating (4.7 vs 4.1) and update cadence (fortnightly vs every 2 months). Multi's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (11.4 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
