Summary: Easier to learn framework with a strong focus on mobile web / apps. Has a larger corporate backing / partners, and is integrated with Adobe Dreamweaver CS 5.5.
• Much easier to learn as compared to SenchaTouch
• Newer version has good basic themes and Themeroller makes custom theming easy
• UI controls appear better focused on mobile devices e.g.
- By default labels are above the text input boxes which preserve real estate on mobile devices
- iPhone style Flip switches work out of the box and allow text on both sides of it Ref:
- Placeholder text for dropdowns works as expected (broken in Sencha touch)
• Less Object oriented / more web site programming like when it comes to wiring events etc. For non-trivial applications, it may almost require using another framework such as backbone or Knockout
• Rough at the edges, Transitions may flicker and sometimes are not smooth
• Some UI controls do not work very well (Fixed toolbars that are overlaid everytime on vertical scrolling make the UX very flaky)
Summary: A more robust OO style architecture with a strong focus on mobile web / apps.
• True MVC style architecture
• Takes a SASS based object oriented approach to theming
• Much smoother / flicker free transitions than JQM
• Nicer iPhone style theme and icons (better than JQM's, IMO)
• Steeper learning curve, changes from Sencha 1.x to 2 in coding styles etc. do not help
• UI is more oriented towards web design than mobile design e.g.
- Form style UI layout with labels on the side of text boxes
- iPhone style Flip switches (Toggle in Sencha world) require .css changes (https://github.com/tomalex0/SenchaTouch-Form-iosToggleField)
