I agree. Org mode will be more efficient and definitely much more feature-rich if you already keep Emacs open all the time, and especially if you bother configuring it properly.

Taskwarrior looks like it can work better "out of the box" and definitely more useful for someone who isn't Emacs-proficient.

Org-mode, for better or worse, is flexible enough to support lots of different kinds of workflow. It's cool if you know what you want to do, and the defaults will be enough for simple GTD workflow, but if you aren't sure how to properly organize yourself, you'll find yourself searching a lot for ideas from other people.

My current org-mode config looks like this: https://github.com/TeMPOraL/conffiles/blob/master/emacs26/.e....

You can think there's lots of stuff in it, but frankly, this is mostly on the lower end :). Most of the code is for tweaking tasks, clocking and agenda views to better fit my workflow. It's by no means finished - living in org-mode is very much about slowly discovering your ideal workflow and molding Emacs around it :).
