To address the "started using newer versions of Node and Chrome" point, since NW.js v0.13, on the day a new version of Chrome hits the stable channel, a new version of NW.js is released matching the Chrome version. At the time of those releases, NW.js ships the current stable version of Node. So as of late, NW.js has been ahead of Electron in being more up to date with Chrome and Node. There is also a corresponding beta version of NW.js that tracks the Chrome beta channel.
