At http://my.opera.com/ODIN/blog/300-million-users-and-move-to-webkit http://my.opera.com/ODIN/blog/300-million-users-and-move-to-... they state they're switching because they feel it is a waste of resources to maintain their own rendering engine. I'd be surprised if the JavaScript engine was a big factor in their decision. The vast majority of "JavaScript" problems encountered by web developers are either problems with the DOM implementation in general. A smaller portion are in the binding between the DOM implementation and the JavaScript language, and fewer still are in the JavaScript engine itself.
