GWT vs RichFaces

[Praveen Sharma]

Off late I have been working on GWT, GWT EXT, Smart GWT to develop an appplication which basically needs a desktop type look and feel. While working I have not really become a fan of GWT as there are problems and things dont appear as easy to implement.
Hence I started looking for some other frameworks which will help me implement Rich client for my project. I came across RichFaces.

Can anyone tell me which is better among GWT and RichFaces ?

You could also suggest me the best framework to use to develop rich clients.

What I am looking for is that the framework :
- should be easy to use
- should have enough documentation

Look at ZK, it is an AJAX based RIA framework that works with XUL templates:

Really cool (at least for the vids I've just watched). I've just finished a simple sample CRUD in Grails, great and easy. Since Grails is the talk of the town, I feel more biased with Grails. But Aribaweb is just awesome!

Anybody used aribaweb here? what do you say?
