Verdict
The clearest difference is price: Immersed Agent at Free against HTML Previewer's $5.99. Immersed Agent also leads on iOS requirement (15.0 vs 17.0). HTML Previewer's advantage is update cadence (every 4 days vs every 3 weeks). On ads, in-app purchases and device support there is nothing between them.
