@neon There's books! "A Byte of Vim" https://vim.swaroopch.com is like a practice-every-day music book.
"Practical Vim" https://pragprog.com/book/dnvim/practical-vim is a tech manual.
It's "emacs vs. vi", Vim's just the most popular reimplementation of Bill Joy's vi. The very short "why?" is vi's an efficient editor for touch typists with just a few commands, and gets faster & more efficient the more commands you learn.
Emacs is a slow lisp interpreter with a slow editor, that does many things poorly.
