The only frameworks worth a sec of my time are now AngularJS , ExtJS , CanJS and Knockout. I must admit, if the framework you are building doesnt have 2 way databing , it is not worth my time anymore. After something like AngularJS i cant go back to wiring templates and data by hand. Polymer looks great but did not work when i tried it. ReactJS , i dont like the use of JSX,and if you dont use it things get verbose. I used to use Backbone , but without 36 plugins it is worthless in a large scale app. Waiting for the final v1 of EmberJS too.
