blocking vs. non-blocking sockets asyncrouns vs. syncournes communicaition

1)what would be the advantages of using non-blocking sockets over blocking sockets?

2)what would be the advatages of using beginSend/beingReceive with a blocking socket ?

im building a client-server chat applicaition with blocking sockets ..
now what im trying to grasp would be the advantages of using non-blocking sockets or asyncrounous methods

-if i use non-blocking i still need to loop threw the meaage to send it all..so with blocking sockets it would block and mybe not half to loop at all threw the send operaition
- if i use being send , the endsend blocks untill done(so whats the point?) plus in order to check if all the packet was sent i need to check it in the asynccallback method and recursivly call it again if necesry,witch seemes like alot of over head when as i understand the callback is done on the threadpool so the message would have to wait untill a thread is availble in order to send it'instead i got a thread looping endlessly and sending messages

i could see the advantages of using beingSend / beginReceive for the reponsiveness of the program but i cant seem to find a way to return the bytes sent from it ?

it returns IAsyncResual but is there a way to return the bytes that where sent threw the result ?
