Verdict
The clearest difference is rating: WBMS at 5.0 against BMS Tool's 4.0. WBMS also leads on in-app purchases (none vs 1) and ads (none vs shown). BMS Tool's advantage is update cadence (every 6 weeks vs every 24 months) and ratings volume (8 vs 1). On price, device support and iOS requirement there is nothing between them.
