Korean Catalog (Kpc) Vs Michel?

Does anyone who knows South Korean stamps fairly well know if the Korea Postage Stamp Catalog (KPC) lists more varieties than does Michel for South Korea, particularly from post-Korean War to, say, the 1970's?

(I would not be surprised to learn that the KPC lists more early (classic era) varieties, and possibly more for stamps issued during the Korean War.)

The reason for the question, is that I have Michel, SG & Scott, but don't have the Korean catalog, and am combing through a collection for varieties.

Thanks in advance for any and all help!
