The ease of use, how well it syncs to my Google Drive and is fully customizable. It can be expensive but worth it if you need something more robust than Microsoft SharePoint. I would highly recommend this program to anyone looking for an easy way to organize files. You will love how organized everything is with AIM. How fast it is! Very efficient. We used to have to email files to each other via our Outlook emails which was very time consuming. With AIM we can now send files to any person or department in real time and it's saved us so much time.
