Verdict
The clearest difference is review sentiment: QR Debug at 100% against CodeRun's 0%. QR Debug also leads on in-app purchases (none vs 3). CodeRun's advantage is update cadence (every 5 weeks vs every 15 months) and iOS requirement (12.0 vs 14.0). On price, ads and device support there is nothing between them.
