After just a few days, you get a much more useful forecast than a percentage alone — especially with the complication enabled. IMPORTANT Accuracy improves with regular use.

Verdict
The clearest difference is price: BigCode at Free against BatteryMonitorComplication's $0.99. BatteryMonitorComplication's advantage is update cadence (weekly vs fortnightly) and iOS requirement (17.6 vs 26.0). On ads, in-app purchases and device support there is nothing between them.
