What's the point of tribalism? It's a natural human tendency to be protective of what's close to your heart and reject things you're unfamiliar with.
Every single HN post about either Emacs, IntelliJ, Vim, VSCode, or Atom always gets riddled with disingenuous comments of people who liked one thing more than other things. Things they either haven't tried or had some cursory experience with them.
These tools are very individual [just like toothbrushes], for someone Emacs offers something that IntelliJ or VSCode can't, for others - nothing is better than Vim.
To truly achieve mastery, one has to try and learn them all and choose a tool that works well for the situation or the one they like (for objective and subjective reasons). Some might say: "that's a waste of time", try saying that to musicians. Go tell James Hetfield of Metallica that he shouldn't be trying all sorts of different guitars because Gibson is hands-down the best.
