I think having Google bundled makes it a clear winner. If Firefox can pay its developers with just the search engine bundle, and it's less popular, it would probably stand to reason that Chrome has paid off much more.
In a world where Firefox is the #1 alternative to IE and Chrome has very weak showing Firefox either asks Google for a ton more money or switches to Yahoo and Google loses a lot more market share.
