Verdict
The clearest difference is in-app purchases: UbetterBMS at none against BMS Tool's 1. UbetterBMS also leads on ads (none vs shown) and iOS requirement (9.0 vs 15.0). BMS Tool's advantage is update cadence (every 2 months vs every 5 months) and device support (4 vs 2). On price there is nothing between them.
