I am confident full ES6 support will be really solid by March 2017. However, the community is moving incredibly fast, some companies are already using ES7 / ES2016 features!
In perspective, transpilers aren't so bad, especially Babel, who's differentiating feature from the start was readable output code.
Today, if targeting modern browsers you can use Maps and Sets. With polyfills[1] you can use the new Array functions, Promises, Symbols, full JS collections, iterators, etc.
