I'm a heavy Todoist user and I think it's great. I used to use org-mode, but all the Android apps I used for it were clunky and had issues with syncing when my file was concurrently edited somewhere else.
Todoist's API is pretty good too, so I've ended up building my own little webapp that fills some of the gaps in Todoist's functionality (e.g. finding a list of the projects that don't have a next action defined).
