Verdict

The call

The clearest difference is ads: B world at none against 7Customs's shown. B world also leads on monetization model (free vs ad-supported). 7Customs's advantage is review sentiment (58% vs 36%) and update cadence (fortnightly vs monthly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
