I used vi/vim for 15 years, and still do when changing configuration locally and remotely, before learning emacs for university work. At work I use Visual Studio, and for personal scribbling I use Sublime Text. I never understood the editor wars.
editor wars are like snowball fights. it only hurts if you take the wrong things too serious.
On one hand, I get editor wars. On the other, it's rather silly. In order to evolve, editors require a certain amount of mind share for their plugins ecosystem. That said once you have a Turing complete language to extend the editor, they're all basically the same in terms of capability.
Those wars are actually quite healthy and productive for the whole, because they make people defend their sides and thus develop their best arguments. They're a great source of information. You just have to be careful not to get emotional and/or degrade to name-calling.
