No it's not, but the continued existence of both is historical. To be 
honest, the two have very different design goals: CSS is made to select 
very fast in dynamically rendered situations, and in order to get there 
it is vastly underfeatured and in a number of cases very ad hoc compared 
to XPath; XPath on its side is meant to be elegant and generic, and 
while it'll be slower it gives one much much more expressive power.

So, I don't think it'll be possible to make everyone happy by chosing 
one, especially as both have strong active communities. We'll have to 
find a third approach.
