I think that doing xhost local:root is better.  There are 2 reasons for
this: 
 1. You're specifying a user name, which gives added security if you've
got a multi-user system.

 2. You're specifying a local connection, not a connection that uses a
network interface.  The X server connections with use Unix sockets, not
TCP sockets.  This gives you less overhead since you don't have to send
all your data through a TCP stack.
