Which is better precision or recall?

Precision can be seen as a measure of quality, and recall as a measure of quantity. Higher precision means that an algorithm returns more relevant results than irrelevant ones, and high recall means that an algorithm returns most of the relevant results (whether or not irrelevant ones are also returned).

Which is more important precision or recall?

Recall is more important than precision when the cost of acting is low, but the opportunity cost of passing up on a candidate is high.
