Verdict

The call

The clearest difference is price: EspBlufi at Free against S3 Browser's $0.99. EspBlufi also leads on iOS requirement (10.0 vs 15.0). S3 Browser's advantage is update cadence (fortnightly vs every 2 months). On ads, in-app purchases and device support there is nothing between them.
