See for yourself by reading reviews on the most popular resources:
I love the ease of typing on the PDF, I'm still learning how to send it to others with fill in blanks. But I like it. Pricey for the redaction ability but I suppose better than Adobe

PDFfiller Fills Needs My overall experience has been positive and if the cons are minimal. It's easy to use and allows me to make necessary additions or changes to documents with a minimum of fuss. Sometimes getting the font to match is a little challenging, but it's easier than trying to "fix," documents with white out and hand print information.
