Verdict
The clearest difference is ads: 25Tasks at none against Opinion Ninja's shown. 25Tasks also leads on review sentiment (100% vs 71%) and rating (5.0 vs 4.7). Opinion Ninja's advantage is update cadence (every 5 weeks vs every 9 months) and ratings volume (52 vs 4). On price, in-app purchases, device support and iOS requirement there is nothing between them.
