Verdict
The clearest difference is rating: PDF AutoScroll at 4.3 against Good Survey's 2.5. PDF AutoScroll also leads on review sentiment (56% vs 38%) and update cadence (every 2 weeks vs monthly). Good Survey's advantage is price ($1.99 vs $5.49) and iOS requirement (13.0 vs 16.6). On ads, in-app purchases, monetization model and device support there is nothing between them.
