Yes, there was a time when I took pride in that too. Then I realized how much more effectively I could use that cognitive capacity if I was applying it where it was best used rather than where my tools forced me to spend it.
But you are right if a tool is just as good in its default configuration then it's harder to justify the investments to learn another one.
On the other hand Emacs has been here for dozens of years and it still mostly works and behaves the same. )
