Notion's novelty according to me is the fact that everything can be a potential document. Notion's as a product has two very contrasting features. One as a hybrid document editor that combines the goodness of Markdown of Dropbox Paper with a more extensive set of formatting blocks. The second as a task manager and an organizer like. Trello.

Every table on Notion can have multiple views saved for previews with different filters, sorting and table style applied. Also, elements in a table can also be a page making it easier to have a Kanban-style sub-task manager for a particular subtask on a Kanban board for your project.

Both Asana and Trello support Kanban style project tracking. Trello is Kanban-only project management, knowledge management, actually card-management tools. Asana is much more complex, supports different project management approaches, well integrated and helpful for any style/type project.

We choose Asana finally, but still some projects kept in Trello

I loved Slack. We used it for discussion. But somehow, it was always difficult to get things done. HeySpace is what replaced Slack and Trello as it combines the functionality of both tools.

So, now we keep on discussing as we did on slack, but once we to a point where we want to do something, we create tasks on a board and distribute them.

trello has a much simpler interface and easy to learn for any team member. asana might have more features and configuration options but do you really need a complex system for developers to manage tasks?

After Microsoft took over trello, it has become more restricted these days but still good for startups.

Keep it simple! Focus on your product, not tools.
