The netsend group pass pd messages terminated with a semicolon, while 
the OSC group use the Open Sound Control protocol
to pass floats, integers or strings, with a path-like address.

The OSC objects only use UDP, butI made an alternate set
(at http://pure-data.cvs.sourceforge.net/pure-data/externals/mrpeach/net 
and http://pure-data.cvs.sourceforge.net/pure-data/externals/mrpeach/osc)
that let you use either UDP or TCP.
Also my net objects take lists of bytes (really floats because pd 
doesn't have bytes) so any kind of message can be sent/received.
Netsend is the easiest to use if you want to communicate between pd and 
pd, or max. Most audio synthesis applications (csound, supercollider, 
etc.) can only handle OSC over UDP.
