I don't know if its changed, but nginx was also supposedly better at 
managing more concurrent, long-lived connections (such as websockets).

My understanding is that is because nginx used a limited number of 
threads to manage all the sockets, where Apache used a 
thread-per-connection model, using more resources per connection.

Things may have changed since the last time I looked at the difference.
