Verdict
The clearest difference is in-app purchases: OS Revision at none against Readle's 9. OS Revision also leads on ads (none vs shown) and update cadence (every 5 days vs every 3 weeks). Readle's advantage is iOS requirement (15.0 vs 26.2). On price and device support there is nothing between them.
