Verdict
The clearest difference is rating: DeviceRadar at 5.0 against LightBlue®'s 4.3. DeviceRadar also leads on iOS requirement (14.0 vs 16.4). LightBlue®'s advantage is in-app purchases (none vs 3) and update cadence (every 3 weeks vs every 7 months). On price, ads and device support there is nothing between them.
