I chose this over GoodReader

I started out using GoodReader for keeping local copies of PDFs for my study materials. I thought that app was pretty nifty and I was happy with using it, despite its power user quirks and not being able to figure out how to get synced folders not overwrite instead of duplicate.

Then I remembered I had Documents and have it a shot. I already had purchased Readdles Scanner Pro and PDF Expert so I had full capability from the start. I realized both apps fulfill the same need and spent time testing each one, specifically how my Workflow would be with documents stored in a WebDAV folder and needing to have local copies even if I had no internet, plus testing the PDF markup capabilities. Both have their own way of handling the available PDF tools, but I found the interface and "simplicity" of Documents more appealing. So, I moved everything from GoodReader and havent missed it since then.

I spend all day looking at documents and numbers. I dont like my apps to feel like a technical paper.
