I believe applymap() could show a much better performance, since it can be potentially executed on the distinct values only, not per table record.

There are two advantages:

1) Applymap is faster

2) Applymap is easier to understand - I always have to think carefully before I manage to write a correct Lookup call, but with Applymap it is always right on first try.
