Verdict
The clearest difference is price: Green Campus at Free against Html Preview's $2.99. Green Campus also leads on iOS requirement (12.0 vs 17.0). Html Preview's advantage is update cadence (every 6 days vs every 3 months). On ads, in-app purchases and device support there is nothing between them.
