Who's better? Jean-Luc Ponty or Eileen Ivers

I've been listening to Jean-Luc Ponty for years now but recently came across a CD which is quite good called "Crossing the Bridge" by Eileen Ivers (it's on the Sony Classical label). She did a lot of the fiddle work on the original River Dance project. Just wondering who everyone would vote for as best violinist, Jean-Luc Ponty or Eileen Ivers?
