Pros: Reach Widgets Library, NO DTO(in comparison with GWT and AngularJS), no JS scripting, DataBinding (bi directional if needed), relatively fast, the amount of code to implement something is the smallest among (GWT,AngularJS,JSF), good documentation and alive community. Cons: some serverside overhead (CPU on rendering and memory on storing state), it takes time to learn it (cause the approach is a bit different to most things you've seen before), relatively high network interaction, a bit harder to apply styles. Bottom line: If your amount of clients is less than ~10 000, your UI controls are not too complex and you don't need a perfect HTML (e.g. you are writing application for internal usage) - this is the best framework you can find.

Great project, the best you can find for this purpose on the market. Much faster than JSF, much easier than GWT. Only downside is that some features are only for PE/EE, but what you get as CE under LGPL is already awesome.
