you are kind of forced to use bower.

lacks older browser support

mixing it with other virtual-dom libraries like react is not easy or straightforward.

What's the definition of "older browser" here? As far as I know, polymer also uses a polyfill [1] to provide the web components functionality to older browsers.

Yeah, but last time I checked it fails: for example there isn't a way to polyfill shadow DOM...

The difference between the webcomponents.js polyfill and webcomponents-lite.js is precisely that the former includes the shadow dom polyfill.

Polymer 1.0 doesn't use shadow DOM (unless you ask it to). Instead it uses this thing called 'shady DOM', which is roughly equivalent but requires accesses to the DOM to go through APIs.

See here for the details:

No support for IE9 even with polyfills. Some people can get away with not supporting IE9, but sadly I am not one of those people.
