Which one should be used : Mojarra vs. MyFaces

[Agam Dass]

Hi,
We are also using myfaces for JSF 1.2 reference implementation in our UI
framwork project. Now we have a push that we should replace it with Mojarra
project implementaion. What do you suggest about these two implemenations
w.r.t. JSF 2.0.
thanks,
Agam
