At my company, over the last 6 months we've tried Trello, Pivotal, and Sprintly. At past companies I've used Trac, Jira, and Asana. And for the last 7 years I've kept a daily todo.txt, where I append today's date and the 1-2 things I want to try to get done, adding detail as I figure out plans. (This is the only task tracking tool I've recommended that coworkers adopt and are actually using years later)
I've come to conclude that no tool for this will ever satisfy everybody's needs perfectly. Part of that is that everyone has different priorities for their task tracking tool. And frankly, some of those priorities are directly contradictory. What's trackable and detailed to a project manager who lives in the task tracker is heavyweight and clunky to an engineer who sees it as a bookkeeping annoyance. My personal todo.txt is exactly me-focused and only changes when I want it to, but it scales to exactly one engineer.
I think you just have to pick something and use it. Changing tools just adds friction and costs you familiarity. Ideally, the people who have to interact with it the most choose the best tool for them.
