@shinmera idk about "need", but I definitely feel better when my tool of choice is popular, and try to justify it to others when prompted to do so. Whether its a programming language/OS/editor/keyboard, the more people use it, the more support it gets, and in the case of programming languages, the ecosystem benefits from lots of people trying lots of different things.
That being said, I try not to force my favorites on people who didn't ask, because that's no fun for anyone involved
