I use Trello, and then I have it sync with Google Calendar. That way, I can handle individual tasks with the flexibility that Trello allows, but use Google Calendar when I need a broad picture of due dates.

For me, to-do lists are far too limiting. Trello strikes the right balance, however, when it comes to customizability.

+1 for Trello I link to Google Docs for anything I can't fit into it.
