Pro Wicket author Karthik Gurumurthy speaks about "Wicket, Tapestry and JSF side by side" in this video recorded at the Indian IndicThreads conference.

I haven't watched the whole video, so I will let you be the judge on that. The video is rather low quality and the audio is not too good: it seems like it was not recorded from a microphone in the direct vicinity of Karthik but from somewhere in the audience.
