Verdict
The clearest difference is rating: PDF Studio at 5.0 against Vision3D's 4.2. PDF Studio also leads on in-app purchases (none vs 1) and review sentiment (100% vs 67%). Vision3D's advantage is ads (none vs shown) and update cadence (every 5 days vs monthly). On price, monetization model and iOS requirement there is nothing between them.
