Because a couple people here have expressed curiosity, here's what I like about org-mode.

1. The workflow is key. From any document, if I want to note down a task, I use org-capture. This creates a to-do item in To-Do.org. Alternatively, I can use org-capture to create a blog post, or an item for org-drill, or whatever. In either case, I don't break my flow of thought.

org-capture to create a new task looks like the equivalent of "task add" on Taskwarrior, except you do it from anywhere inside Emacs, not from the command line.

2. The org agenda shows all upcoming scheduled tasks. I also use org-habit, which are just repeating tasks that show how often you've completed them (and can prompt for a note when you mark it as done - "30 pushups" for TODO: exercise, or whatever).

3. I can "clock in" on a task in To-Do, and when I'm done archive the task in an automatically-created archive file. I can then see total time worked on that day, broken down by task. When clocking in, org prompts me for a time estimate.

4. Because all tasks are just bullet-points, I can nest sub-tasks, and expand or collapse them, like the app Workflowy. The top-level task can show percent or fraction of sub-tasks completed.

5. Best of all, at the end of the day, and despite all this manipulation, it's just text. I can edit time spent on a task, or whatever. There's no hidden magic.

This workflow is pretty GTD-ish, because it helps you get everything out of your head on the fly, and break things down into sub-tasks. It also works well with SRS and incremental reading. I see myself sticking with this, but I've used other systems productively, so whatever floats your boat.

It allows you to implement GTD or pomodoro. I admit it will take a few hours to do or get a hang of, but it's among one of the goals of Taskwarrior to stay methodology agnostic.

care to make a more detailed comparison between this and org mode ?

I too would like to hear about how org-mode is an effective task manager. On its face, it seems like grandparent is saying "This doesn't compare with the power of Markdown for managing to-dos." One is a tool, the other is a formatting language.

If you're implying that TaskWarrior is a tool and that org-mode is a formatting language (or file format), then you're way off to begin with. Org-mode does have a specific format for its files. But much of its power derives from the tools it incorporates. E.g., the org-mode Agenda functionality enables complex searches over multiple files and collects and orders the results in a single buffer, and allows users to perform operations on the results (i.e., on the original buffers containing the results) directly from the Agenda buffer. There's much, much, more. Org-mode is primarily a tool, not a file format. If you want an overview of some of its functionality, you can take a look here: http://doc.norang.ca/org-mode.html

Org-mode has embraced the emacs philosophy with respect to workflow management. It is a document formatting language which has been co-opted into doing pretty much all aspects of workflow management -- tasks, reminders, calendars, etc. I personally don't think it does a very good job, but some people swear by it.

Why do you think so? Would you care to elaborate?

I posted above why I like Org-Mode. Here are a few things it doesn't do well.

1. Because it is text-based, its visual summaries are limited. Like, there's a calendar, and for org-habits a simple color-coded chart to show consistency, but that's about it. If you're looking a week or a month ahead to visually see how many tasks you have coming up, the org-agenda is text-based.

2. While org-mode can sync with Trello, Beeminder, and a couple other task-management systems, its integrations are pretty limited. If you want to integrate with Contacts or whatever you'll have to work a bit.

3. org-mode's part of Emacs, so you'll need to be comfortable with Emacs.

Contrast this with Sunrise Calendar. Sunrise Calendar grabs gmail messages and appointments, iCal, google calendar, and displays them all nicely.

Pluses and minuses, depends on your needs and what you like.

Org mode is a tool. It's got a formatting language in it, but it provides calendar, schedule, time tracking, workflow management, and more.

I'm not the most familiar with either, but one of the simplest differences is that org-mode allows you to have entries longer than single lines and have it formatted. This is immensely more helpful when implementing GTD IMO.

Org-mode can also easily become your calendar as well, which Taskwarrior cannot.

The only thing I miss in org-mode is a more powerful domain-specific language for events. Like remind, which is a very nice Unix GPLed utility:

Why not? Taskwarrior has time scheduling, due dates and a calendar.

Not at a level lower than a day.
