Tell you the truth, I've used Emacs for a long time now (~10 years) and I don't know if I use the C-{n,p,f,b} or arrow keys. I'm more likely to move in larger chunks: search, move by word (M-f, M-b), line (C-a, C-e), etc. If I need to edit a word, I will kill it entirely and re-write it.
same exactly for me, i use sometime the arrows or the other keys or c-s etc.... i don't mind the jk vim keys as well when i am in vim, either way it's all about your brain being good enough to context swift in .... context
