JBoss Seam vs. Oracle ADF

Well, now I've seen two sessions with two very different frameworks heading for the same thing: make the development experience of today's java applications easier. Gavin King did a very comparable demo to Shai Schmeltzer: some JPA stuff, some JSF stuff, binding them together. Seam looks interesting, but I have to think about some reasons why I would use that. ADF in comparison, looks much more integrated on the first view and has much better support in the IDE. The ideas and what you do, are likely the same, in both cases.
