Verdict
The clearest difference is ads: WFワットチェッカー at none against Barcode Detection's shown. WFワットチェッカー also leads on device support (3 vs 1) and iOS requirement (12.0 vs 17.7.2). Barcode Detection's advantage is update cadence (fortnightly vs every 2 months). On price and in-app purchases there is nothing between them.
