Functionality, like memory allocation and usage, animations, and a variety of other options, will define what a good HTML5 framework is. This framework does offer good access to mobile phone devices, such as the camera, or some other internal information that only a native app could previously access. These factors go far in deciding the type of framework to use.
Just because some frameworks or JavaScript libraries are popular in one area does not necessarily mean they are not required in another. For example, the jQuery JavaScript framework is very popular due to many programmers having used it in the past for large or small projects.
It will be difficult for an end user to distinguish native and HTML5 development when the app is running. However, the way it is installed will determine whether it is a web or native app. Not that it matters to the end user, but users expect a great look and feel, richness in technology, easy and quick navigation, and that the app actually solves their issue, which is the functionality of the application in the first place.
