Verdict
The clearest difference is in-app purchases: ONE Device at none against Runestone Text Editor's 1. ONE Device also leads on rating (5.0 vs 4.7) and iOS requirement (13.0 vs 15.0). Runestone Text Editor's advantage is ratings volume (2K vs 3) and update cadence (every 2 weeks vs monthly). On price, ads and device support there is nothing between them.
