Yet somehow every Trello clone I've used has never been as fast, intuitive or as simple as Trello. You're either fighting against a poor UI, slow animations or in some cases visible reloads when dropping cards.

If Trello is such a simple product, how are the competition failing to make their version as refined? I've never found a single competitor that has made their Kanban board feel like Trello, so until then, I'll just keep using Trello.
