In a nutshell, Mulberry is more opinionated than Sencha -- by being opinionated, it makes it much easier to get an app up and running without worrying about the underlying architecture of the app.
Mulberry expects that you're creating a content-centric mobile app, and so it expects you to define your application in terms of nodes that have assets associated with them -- assets like images, videos, audios, feeds, and data. Nodes are the building blocks of a single-page application that Mulberry creates inside a PhoneGap wrapper. Nodes are displayed with templates, and templates consist of components. You can use the components that come built-in with Mulberry and write very little code; however, you can also create your own components to add custom functionality to your app -- this is where Mulberry's true power lies (see the blog post for details).
Speaking more generally, Mulberry is aimed at developers who aren't interested in spending time on the low-level architecture of their application -- things like data stores, views, etc. Instead, Mulberry is aimed at developers who want to create their content, create their assets, create their data, and then write simple JavaScript and CSS that presents that content and data in the ways they need.
