Verdict
The clearest difference is review sentiment: Pudding Scan at 91% against PDF Scanner's 36%. Pudding Scan also leads on rating (4.9 vs 4.5) and ratings volume (210 vs 21). PDF Scanner's advantage is monetization model (free with in-app purchases vs subscription). On price, update cadence, ads and in-app purchases there is nothing between them.
