Big part of the appeal is keeping your hands on the home row all the time, without having to reach for the arrow keys. HJKL for movement makes all the difference for keeping focus on the writing, not having to reach out to the arrow keys when wanting to move or communicate motion. This combined with the excellent text manipulation features right there from the keyboard, without leaving to menus, being able to just flow with the Vim -keybindings, and in all different IDEs and editors that support Vim -support, it's just great.
