For me, personally, ActiveCollab is the best task management tool as I have been using it for the past 4 years. The UI is very user-friendly, and creating a new task and especially recurring tasks is the best option, as I have to deliver weekly reports to my clients, and I have never forgotten any report in the past 4 years, as the weekly and monthly tasks are automatically created and assigned to me. The second best option is that we can edit messages in a limited time-frame, not whenever anyone wants it. Thirdly, the "reassigning" option, which keeps everyone in the loop.

It's very ewasy to use, it was easy to implement in our company and it inegrated nively with Hubstaff (timetracking). It has a ton of features that that makes it easy for our team to manage calendar and how we use the platform.

ActiveCollab is excellent when we talk about implementations that do not require the use of hardware infrastructure in our organization since we can use it from its 'on cloud' implementation, this gives us additional functionalities such as workload management and timesheets, through a waterfall project work methodology. There is a lot of documentation available online that helps familiarize us with the different options and functions, as well as informing us about the use of templates, to mention an example. Its configuration of roles and permissions is quite robust, making it easy to define what a user can do in activeCollab since we have five predefined roles in the system in addition to being able to adjust them based on the particular needs of a project. On the other hand, we can invite members and collaborators through email notifications and assign them tasks, upload documents that support the activities and in general we can create a design that allows us to manage the execution of our project in a simple and efficient way.
