I have completely given up on DefinitelyTyped/Typings/@types. The odds that any non-trivial type definitions are complete, up-to-date, and correct seems to be incredibly slim -- and god help you if you're stuck on a very specific version of an NPM library. I had high hopes with @types but all I have to show for it is an increasingly large file containing modules declared as "any".

Next time I'll go with Flow. Generally the only thing I REALLY need to be typed are the domain-specific models, and so I'd rather be as close to idiomatic JS/babel as possible.
