Verdict
The clearest difference is ads: LeakGuard at none against HTML Viewer Pro's shown. LeakGuard also leads on update cadence (every 4 days vs every 15 months). HTML Viewer Pro's advantage is iOS requirement (12.0 vs 26). On price, in-app purchases and device support there is nothing between them.
