It makes it easier to select a set of elements based on certain criteria (for example all <div> elements with a class of example) in a way that's consistent with how people are matching elements in CSS for instance.
So instead of having to filter what getElementsByTagName returns you can directly filter it in the query. And given that implementations of Selectors are claimed to be pretty efficient it's expected this will be pretty efficient as well and most likely faster than a custom implementation of it.
