Using ng_ksocket is almost the same as using the so* functions, since 
the ksocket methods call the so* functions.  But by using netgraph, you 
  get a nice management interface, too.

For my application, I found that going through the socket layer (the so* 
  functions and/or ng_ksocket) hurt performance too much.  That's why I 
ended up bypassing them.
