What is your preferred product management / roadmapping tool?

So I’ve used trello in the past to get our documentary team on task in post, didn’t need a whole lot out of it, seemed to work fine. Actually the day before this question was posted I had asked around and without much feedback I ended up using this free web based one called freedcamp.com  So far so good, clean, simple, and really customizable. Within the dashboard there’s basically a secondary sub-dashboard where you can install widgets that will perform some of the more advanced or project specific features or integrations from other well known 3rd productivity apps out there.  will update after a week or so of use.
