First, let me say that I'm a big fan of Lodash and still use it in several projects, but for some time now I prefer to write my own helpers or use a custom build of Lodash.
Keeping things simple and dependency free is what I strive for lately. Writing your own helper functions is better than bloating the project with yet another dependency.
That being said, there are still times where using Lodash is the more rational decision:
_.bind is faster than Function.prototype.bind)curry and debounce . Instead of rewriting it, you can just import it.
