I've built a few apps using node-webkit for myself and, being a web developer, found it pretty awesome. One of the challenges that I think atom-shell handles better is background tasks/jobs. In node-webkit, my understanding is if you want to be able to background tasks using a node worker (not a webworker), then you have to bundle another node runtime with your app and use node's execute/spawn. This works OK, but bundling another version of node is kind of a pain. atom-shell works this way out of the box which is awesome if you need it.

Both projects are great ways of developing apps using web technologies though.
