"Best" always depends on your criteria. Very often, the standard library is a "good but not best" solution from a pure performance or features point of view. However, it often wins for ease of deployment (nothing to install), ease of maintenance (the project is not likely to be abandoned), documentation, and standardization. IMHO, C++ in an example where the standard library (and its laboratory, boost) is often a very good solution for the few things it covers. It's standardized, well-documented, and not that bad from a performance point of view (of course, it's not perfect). In addition, you expect your newly hired developers to know the standard library, but not every small libraries from github...
