What are the difference in Cucumber pre-action?

What is the real difference between @Before hook in Cucumber and Background keyword in the feature file? I can think of only one difference, which is Background keyword is specific to only one file, whereas @Before is for the whole Cucumber framework. Are there any other differences?

Quoting the docs on hooks:

Think twice before you use Before

Whatever happens in a Before hook is invisible to people who only read the features. You should consider using a background as a more explicit alternative, especially if the setup should be readable by non-technical people. Only use a Before hook for low-level logic such as starting a browser or deleting data from a database.

While Before and Background can be used to implement the same type of pre-test logic, it mainly comes down to whether or not the setup you are trying to perform is at-all relevant to the test. For example, if you are testing a web application, is there any explanatory power or benefit in starting each test with...

Background:
  Given I have opened my browser
  # ^ internally starts Selenium or a similar web-driver

If not, perhaps it should be a Before hook.
