short answer - 

1) eval (most of the time) completely replaces any values in the
recieving variable.
move, takes into account the length of the from and to variables to
know what part of the reciever gets replaced
2) eval left justifies, move right justifies.

long answer, you will just have to RTFM.  Not much choice here.
lots and lots and lots more, all dependant on variable attributes, and
the myriad other uses for eval.
