Verdict

The call

The clearest difference is review sentiment: eSign at 78% against pdfFiller's 20%. eSign also leads on rating (4.7 vs 4.4) and iOS requirement (13.0 vs 15.0). pdfFiller's advantage is ads (none vs shown) and ratings volume (8.5K vs 112). On price, update cadence, in-app purchases and monetization model there is nothing between them.
