Master links/quick links and half-links serve different purposes. The master link/quick link is used to allow opening the chain without a chain tool, while half-links are used achieve proper chain length in situations where a derailluer is not present to take up slack (e.g. tandem timing chains and fixed gear/single speed/IGH set-ups).
