Verdict
The clearest difference is review sentiment: SuperX at 100% against Dual Window's 25%. SuperX also leads on rating (4.0 vs 1.0) and ads (none vs shown). Dual Window's advantage is in-app purchases (none vs 1) and update cadence (every 3 days vs every 5 months). On price and device support there is nothing between them.
