not only the above reasons guys....
.
but also the following.
.
Y-D Transformer is preferred as most economical rather than
the both . reason: D side always preferred low voltages as
it has Vph = V line to line. it want more turns ans more
insulation to get that line to line voltage ..

similarly Y side high voltage can be used as phase voltage
is much less than line voltage, takes less turns and less
insulation to get required line voltage
