I've been a very happy neovim user for over a year now (on linux).
My switch was pre-vim 8 so the ability to have things (like plugins) run asynchronously was a huge plus, but now vim has that too.
For me the biggest selling point is the plugin architecture, I've been a vim user for over a decade now, and I'm only writing my own vim plugins now, because neovim allows me to do that in the language of my choice (ie. not VimL).
