I did too. Taskwarrior is just so streamlined for todo's. I always felt org-mode was pretty clumsy at that, in comparison. But maybe I just don't know org-mode well enough. But that itself is symptomatic of what a steep learning curve org-mode has to take full advantage of its more adavanced features. Taskwarrior was much easier and quicker for me to learn, and has a boatload of features to rival org-mode, as far as task-oriented features go.

I do wish Taskwarrior was fully integrated in to Emacs, as org-mode is, but that's the way the cookie crumbles.

I still use org-mode for all my notes, though.
