COB potentially has four times the cobalt that N27 has, and its sulphide with minimal impurities. They're both winners as far as my limited knowledge is concerned, so having money in one, the other, or both will serve anyone better than cash bonds. It's like holding Facebook and google, except you get the same gains in six months instead of five years. It's a tough life when you have to consider CGT implications when selling.
