You are right if you are comfortable with your editor you're not missing a lot. I tried Emacs for a while it's nice and comfortable the moment your brain get used to the keyboard shortkeys though since it's a different word you start running everything in Emacs and it becomes your OS. Why it can be a problem is another story. Anyway I switched back to use different tools for different jobs. For taking notes and managing them I use Joplin it supports markdown, todo lists, etc. and you can even copy paste images into the editor. Lots of other features as well as sync with different backends.
