Verdict

The call

The clearest difference is in-app purchases: SlideId at none against Runestone Text Editor's 1. SlideId also leads on iOS requirement (13.0 vs 15.0). Runestone Text Editor's advantage is update cadence (every 2 weeks vs every 2 months) and chart position (#47 vs unranked). On price and ads there is nothing between them.
