Can someone concisely explain to me the benefits of a very javascript heavy way to build your mobile app like Sencha-touch over the more HTML5/CSS based way of jQuery Mobile and Bootstrap?

Also I'm confused why this article failed to mention two of these frameworks

I've been doing a lot of research over the past week on all the solutions out there because I'm building a phonegap based html5 app. My goal is to make it as native feeling as possible. The closest to that experience comes from Sencha Touch and Spine.js mobile. However, what I have found is that doing things from scratch is really the best way to get as close to native as possible.

Sencha touch is a bit heavy and you have to do things their way, and there's a bit of a learning curve (not to mention it doesn't mesh well with a lot of the javascript MVC-style frameworks out there). That said, it really is the most complete, best performant option out there.

This article was a fail in that it failed to mention sencha touch which is the no brainer choice in this space.

Jquery mobile comes second after this.

That's an interesting opinion. How do you feel about the fact that Sencha touch requires the purchase of a license for a commercial app whereas jQuery Mobile does not? IMO that makes jQuery a more attractive choice.

However, I will agree that the article was a bit jQuery heavy; several of the options presented were extensions of jQuery Mobile.

It does not now. Sencha updated their commercial license to be free.

I feel like Bootstrap should be added to this list. The included CSS and Javascript is amazing and makes development incredibly easy.
