Tapestry and Struts

Hi,
Has anyone experienced using both Struts and Tapestry? I am interested in trying out Tapestry because I am always interested exploring other
alternatives that will help my work in the long run. So far, I've read many good things about this framework (now a sub-project from Jakarta) and was wondering what others have to think about it in comparison to Struts. I know it requires a steep learning curve, based on various people's comments, but it's not like in life everything is already laid out for you.

Would like to hear any comments from anyone.
