Which library to choose: AngularJS Dynamic Form Generation based on JSON Schema

I am planning to build a generic Web + Desktop + Mobile solution for organizations that heavily do surveys and data collection and generate reports based on collected data (e.g. Non Profits).

The solution needs to be centrally controlled and synced, can work offline and can be used on any device supporting HTML5.

Dynamic Form Generation will be a core functionality for this product. I've been looking for a library that supports generating mobile ready forms. Given AngularJS + Bootstrap are promising in this regard, I came across:

1. formly-js/angular-formly
2. Textalk/angular-schema-form

which looked popular on GitHub Explorer and seemed very mature to provide the desired functionality. I need guidelines to which to choose, or should I go for some other solution?

If you have experience working on such a project, what would you suggest me, which technology stack should I use, given the following aspects of the product:

1. As mentioned the product should run on any HTML5 supported device.
2. Forms and Data access can be controlled from server/cloud per user.
3. App should work offline and when finds internet, should sync collected data with server/cloud.
4. There will be a form designer for Administrators to visually build forms and any newly designed form should instantly get available to data entry devices.
5. Collected forms data will be used to generate Reports (Publish to Web, Excel, Interactive Charts etc.).

To address Offline behavior, Controlled Access, Syncing and HTML5 support, Sencha Space looks compelling, any thoughts?
