I like using Emacs because it does everything. Sometimes not well and you have to let it go, for example I wouldn't imagine managing Java projects in Emacs. But there's a world of discoverability and learning in Emacs that's unmatched in my opinion. The writing experience is especially excellent, I write all my notes and presentations in Emacs, they can be linked together, compiled to PDF or Word, use interactive code blocks and much more, it's fascinating. It also made me interested in subjects I didn't know about like knowledge management and the history of Lisps, thanks to its community.
