I would also love to see some comparison between different js frameworks. There's huge differences in the various javascript frameworks used in conjunction with phonegap. For instance is famo.us fast and has some good third party widgets, like famous-flex. Ionic is very fast to learn and use, but scrolling isn't excactly fast. If you combine both famo.us and ionic on the other hand, you should be able to get a near native feel. There are efforts to create angular directives for some famo.us widgets.
