Compare PDF fill-and-sign tools

Most comparison pages about PDF tools are written by whoever is selling one. These are written by us, who are also selling one — so every claim about a competitor carries a link to the page we read it on and the date we read it, and every page says plainly where the other tool is the better choice.
