See for yourself by reading reviews on the most popular resources:
Very versatile software for editing (specifically filling in) PDF documents. I looked specifically for software to fill out tax forms and PDFfiller exceeded my hopes and expectations. Good job.

On a day that I was going to really need my PDFfiller, the service was interrupted. My auto renewal had frozen up somehow and I couldn't access the service I was paying for. I immediately contacted customer service and notified them of the issue. To say that they went right into action to fix my problem would be an understatement. PDFfiller - you're service is great. You're customer service is AWESOME. Thank you for not only addressing my issue quickly and efficiently but for going above and beyond to make up for the inconvenience to me.

You need some front end GUI. "What do you want to do?" "Create a brand new form from scratch?" "Make a PDF form fillable for your business?" etc.... I got the service and deleted my subscription only to play with it a little more and see the tiny, green side button that allows one to make the form fillable and then I realized this was a service I wanted. You are not demonstrating or advertising the best feature from the get-go.

What do you like best?
The best feature of PDFFiller is its ease of use, whether it's editing documents, signing documents, and then being able to access your documents anywhere by logging onto the site, as opposed to being constrained if you don't have your computer files with you.
What do you dislike?
Some of the option menus should be improved upon, especially as far as layout and ease of finding what you need, it's a bit counterintuitive though with experience that becomes less of an issue.
What problems are you solving with the product? What benefits have you realized?
Signing PDFs with ease. Being able to access and edit a pdf no matter where I am as long as I have internet access, even if I don't have my computer with me and/or don't have access to my cloud storage.

Super responsive
Have had an account with these guys for a few years now so its about time I did a review. The features are good and I can do all the things I need to edit documents. If something goes wrong they are super responsive and provide fixes/solutions very quickly. Highly recommended.

pdfFiller was useful, intuitive and feature rich. It not only provided access to nearly 100 useful form templates but allowed me to have the ability to edit them right from the site. Excellent!

pdfFiller for document sign
I like the robust feature that pdfFiller provides, fairly simple to use
Limited functionality, rarely see updates to match other features Adobe has
