Verdict

The call

The clearest difference is review sentiment: eSign at 60% against pdfFiller's 20%. eSign also leads on rating (4.8 vs 4.5). pdfFiller's advantage is monetization model (free with in-app purchases vs subscription) and ratings volume (9.2K vs 147). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. pdfFiller sells 10 in-app purchases, starting at $19.99 per month and eSign sells 9 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
