You take it in the wrong way. Some might share with you their experience with one or the other framework, but I don't think you might not get more detailed comparison than this one:

Still, I suggest you better specify your business and technical requirements, and try to match them with your candidates features. And you might also consider the rest of your project: for example the Microsoft platforms are currently enforcing and supporting JQuery.
