I think KEEP option would be the better way to read the
variables that we need. But it's again depends upon how
many number of variables that you want to read from the
input dataset.
Let's say there are 30 variables in data set and you want
to read all the variables except 5 variables from the input
dataset. Then it's efficient to use DROP option to drop
those 5 variables instead of mentioning all 25 variables at
KEEP option.
