Verdict
The clearest difference is review sentiment: QR Debug at 100% against QRU?'s 0%. QR Debug also leads on iOS requirement (14.0 vs 16.4). QRU?'s advantage is update cadence (every 3 weeks vs every 15 months). On price, ads, in-app purchases and monetization model there is nothing between them.
