Well, actually the best implementation of Material Design would be callem'all's http://material-ui.com/. Really mature and full-featured.
vuematerial is slightly behind in the no. of components. After some more research I have settled on using http://www.muse-ui.org/#/index. It has full parity with callem'all's component set. In fact, the website is nearly a full clone of that. And the developer is pretty active.
