This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
Posting this in the JSF forum is likely to give you skewed results towards JSF as its aficionados are the one who lurk here.
Personally, I would only use JSF if a large man were holding a powerful weapon to my head -- and even then, reluctantly. But you are likely to get other opinions -- which is good. Then you can sort through them and make your own decision.
