I’m a big fan of certain aspects of Teamwork’s Chrome extension (it is one of the few times where I think Teamwork’s UI beats out Asana’s). See this imgur screenshot for reference.
I work mostly in Teamwork’s “Create a Task” view. I love that the box is huge, so everything is easy to see.
I also love that you can enter information like Project, Task List (which in Asana would be the task list headers), Task Name, Asignee, and Start/End Date.
The official Asana Chrome Extension doesn’t even let me categorize by projects. Which is a huge pain since later on I have to spend time adding categories to things. It makes me not want to use Asana at the end of the day.
The unofficial Asana extension has all these functionalities as well, but I prefer the Teamwork design because the box is big and easy to use. It feels less cluttered.
tl;dr: Teamwork > Unofficial Assana > Official Assana
