Verdict

The call

The clearest difference is price: WebDebug at Free against BLE Spy's $4.99. WebDebug also leads on update cadence (every 2 months vs every 8 months) and ratings volume (25 vs 4). BLE Spy's advantage is review sentiment (50% vs 10%) and in-app purchases (none vs 3). On ads and device support there is nothing between them.
