For us best feature is out of the box Jira integration. It has been difficult to find a mature PPM tool that has integration with Jira. The Atlassian plug-ins are not quite PPM tools. Additionally we can answer project cost questions in real time based on the work that the resources are accomplishing based on the status of their Jira tickets. Before this tool we had monthly updates in another PPM tool by project resources which was not always aligned with the day to day project progress. In addition to this we also get trend analysis, risk cost (based on the impact on specific tasks or milestones), as well as reports and a built in scope/charter. onepoint also has an REST API that can be leveraged to interface with other internal tools.

What I like best about onepoint is the simplified user interface, when I sit and compare the ones I have used in the past, which have a way bigger name in the market but look so complicated that when you really sit to work on those it is intimidating. OPP on the other hand has a very user-friendly, simplified look, so well adhering to IPMA/PMI standards that you might think you are going through a practical session on PMI's project management process.

The ease of use. Compared to other PM tools, Onepoint Projects is certainly the one with the best work-flow and ease of use. You can build up your custom reports directly from the interface using guided DB queries. There is integration with JIRA for tasks work logging which is great for people already using JIRA. The ability to install on premise was critical for us. Many other solutions offer it only as SAAS.
