While Bear has some cool features, so does Org mode. I personally like that I can author blog posts in it, put in some code in SageMath within my org document, and whenever I export the org file for publishing, it will execute that code.
I like that I can make a note and simultaneously link to an email I have, link to some code in a .cpp file, and link to a Jira ID.
I like that I can log how many minutes I spent on a writing project, and have it automatically enter that data into Beeminder.[1]
And so much more that I'm sure Bear doesn't do.
