I wonder if the different preferences is at least partially due to
whether the person has a hardware or a software background?  The idea is
that when hardware guys see the instruction, they think in terms of
register ports (read versus write), what is required of the memory
system (somewhat different for loads versus stores), etc.  However
software guys think of a language construct, e.g. X = Y, which is
logically a move.  I don't know if this is right, but I think it is
interesting.
