It's amazing how flexible AC can be depending on a project's needs. It can serve as a simple reminder list with great speed and simplicity but also get fully blown up for projects involving production teams and clients at once. Compared to its competition it never feels like its dictating you to use it in a certain way, it just hands you a great bunch of options and lets you use them without interference. I use other products like dropbox and dropbox paper too and it all goes together really nicely.
One thing to note is a personal and genuinely helpful customer service, there have been issues and bugs here and there (not many) and in 90% of the cases they were solved within short time.

I think AC is great for freelancers and small project groups working remotely I switched from Basecamp and it was one of a relief.

I personally don't like the free limitations of users. I know there's a business model behind it but I hate to delete other clients/team members just to make room for someone else.

In such a complex world, where the time and control factor in operations makes a difference, it is vital to have a platform that allows access to many tasks that, otherwise, would involve and coordinate many people, this type of tools allows us to save costs and reduce involuntary human errors, in everything that refers to the necessary coordination between all the members of the project. The calendar allows to have all the tasks, meetings, and filter the tasks by projects, and if that were not enough, all this can be complemented with the participation of the members remotely, so that it is possible to follow the general state of the proyects. In case of any problem, the support team is attentive to clarify your doubts, there are still elements that we have not had the opportunity to explore, but that, surely, according to our needs we will be using them to solve the growing demands of our organizations.

As with many platforms, the versions that are used in tables or smart devices show some limitations, in relation to those that are handled by PC, it would be very important to preserve and maximize the benefits when you have other devices and not limit the functions that, After all, knowledge or traditional devices for solving problems are not always available.

It's a great Project Management System. We moved from a legacy system and had prerequisites for our agency: project & task management, people/roll management and time management. It does these with ease. Then it layered great collaborative working.

The recently launched "workload" feature is an add-on additional cost. As a SaaS the competition is fierce for features and benefits. I personally think this should have been part of their bundle, not additional.
