Honest question: what’s the point of this question? what does it matter?
If “legendary programmers” all chiseled bits into a disk with a scalpel would that make it a good idea?
Use whatever makes you comfortable and allow others to do the same. Don’t emulate or even care about “legendary programmers” tooling.
if you don't learn from the best, how do you improve?
Legendary programmers don’t become legendary because of their text editors but because of the code that they write.
Linus Torvalds has used a janky version of micro Emacs that he picked up as a university student in Finland.[1] Will it make you a better programmer if you switch to his editor? No. Just use whatever you are comfortable with, like he has. He has used this editor because he got used to its peculiar keybindings. He rather worked on the kernel than to learn new keybindings.
