For jumping around what's on screen, I think 'easymotion' ("jump anywhere on screen by pressing two characters") & variations are best in terms of how quickly they let you navigate for how easy it is to use.
To me, if my cursor is a few lines away from another line, the easiest way for me to get there is by either using h/j a few times, or looking at the absolute line number and doing that with gg.
Relative jumps are only useful to me in macros. Calculating a relative jump myself would 100% pull me out of the flow state where I just want to go up/down a few rows.
I have no proof of this, but I’d guess that the creator of this pattern didn’t feel the same way.
While I loved multi cursor with sublime. After I moved to Vim, I’ve never needed it. It’s either search~repeat or a macro. Now I’m using emacs, and it’s mostly occur-mode and macro. Grep edit is nice for bigger refactoring.
I tried evil mode, but it clashes with other keybinding in some places and I got unhappy with it. There's a philosophy conflict there. With vim, you're expected to have a command for an action and then bind it to a key. Your editing workflow is to compose those keys.
But with emacs, you're more expected to have a view and then a set of actions for that view. The power of emacs comes with how easy it is to integrate all those views together. For a programming workflow, you have the file explorer, the symbol explorer, the search result (single file and all files), the version control, the docs, the compilation|build window, the shell, the project tasks,... all together in the same place and linked to each other. With vim, you have to compose all those with a multiplexer and other tools (with conflicting bindings) to get there. Vim is still better for editing, but Emacs is better for workflows.
Or instead of 15j use another jump to command that accepts those letters as numbers
Or have some jump type of command that displays a-z labels 1 per row in the middle and you can jump without numbers and without shifting focus to the gutter
But yes, the most basic motion will still be more "intuitive"
