Verdict
The clearest difference is price: iEditor at Free against HTML Previewer's $5.99. iEditor also leads on iOS requirement (15.6 vs 17.0). HTML Previewer's advantage is ads (none vs shown) and update cadence (every 4 days vs every 7 months). On in-app purchases and device support there is nothing between them.
