Verdict
The clearest difference is review sentiment: OLAF at 100% against QRSticker's 50%. OLAF also leads on iOS requirement (11.0 vs 13.4). QRSticker's advantage is update cadence (every 8 days vs every 3 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.
