Its versatility, all within one file format. e.g. for anyone who hasn't glanced at the Org-Mode table of contents: https://orgmode.org/manual/index.html#SEC_Contents https://orgmode.org/manual/index.html#SEC_Contents For managing tasks: org files can be richly structured. So you can organise a task in some nested hierarchy; or with a tag; or with some key-value property. You can also make use of the way you organise notes to quickly search for tasks. Org also provides some useful ways you can view your organised tasks. Besides task management, it's kindof "2nd best at everything", but all within one file format. For GTD: Org supports a workflow where you can quickly 'capture' some information; then later organise it. Org Babel: supports running snippets of code in an org-file, outputting the results. It's more primitive than something like Jupyter, though. (But you can also re-arrange the code snippets into files, supporting a literate programming style). -- I've found this a useful tool for keeping code and notes together. Org has some support for tables/spreadsheets. I don't use this very much. But, again, useful to be able to embed (and update) within notes. You wouldn't start using org-mode to get all these benefits. You start using a small part of it. And then you notice some other feature of org you'd benefit from, and figure that part out.
