I've been using Emacs for ~5 years now, and I switched from Sublime Text. I used Vim here and there but I wasn't a huge fan, and I always heard that Emacs is _the editor_ that can solve anything. Org mode is what got me really interested so I read through that book and switched to Emacs fully after a couple of weeks of light usage and reading.
Now I only use Emacs, and I've never been happier programming. It's truly a remarkable piece of software.
Edit: just want to say that you should use vanilla emacs and try not to install any plugins at first. Resist the temptation to go willy-nilly on some awesome-xyz list.
Suggest grabbing the emacs book https://www.oreilly.com/library/view/learning-gnu-emacs/0596... and/or the emacs manual from https://www.gnu.org/software/emacs/manual/ (free pdf) and go through them. They will repay the time!
Good luck and remember any pro emacs user will trip themselves up to help newbies learn!
