The power comes from the ease with which you can adapt your workflow to varying requirements.
If this description doesn’t cover areas you need to work in, forget it.
An example: you need to do a bunch of work in a pipeline, but at one point during development you want to stop, examine the output, possibly edit it, and then finish the pipeline. In this case, doing the work in emacs feels good because you can put the intermediate results in a buffer. Not life changing, but nice.
