How is the five kingdom classification advantageous over the two kingdom classification?

The five kingdom classification, that is proposed by RH Whittaker is based upon cell Structure, body structure (unicellular, multicellular), nutrition (autotrophic, heterotrophic) reproduction and way of living either aquatic, terrestrial, or arial and phylogenetic relationship.
So, it is more useful as compared to two kingdom system of classification which does not distinguish between prokaryotes and eukaryotes and no other kingdom except plant and animal are ‘identified.
