Verdict
The clearest difference is review sentiment: Dupefold at 100% against ImageResize's 44%. Dupefold also leads on rating (5.0 vs 4.5) and ads (none vs shown). ImageResize's advantage is ratings volume (228 vs 2) and update cadence (every 2 weeks vs every 6 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.
