Verdict
The clearest difference is update cadence: B.B. Link Configurator at every 5 weeks against ST's every 27 months. B.B. Link Configurator also leads on review sentiment (67% vs 50%). ST's advantage is rating (5.0 vs 4.6) and iOS requirement (12.0 vs 16.6). On price, ratings volume, ads and in-app purchases there is nothing between them.
