Lets try usenet

I have two grammars, one with white space

WS	 : [ \n\t\r]+ ->skip;


and one, or two actually,  for comments
COMMENT: '#' .*? '\n' -> channel(HIDDEN);
COMMENT2: '/*' .*? '*/' -> channel(HIDDEN); //This pulls through
                                            //linefeeds?

What is the practical difference between the channel(HIDDEN) and the skip
