  • ST_Intersects might be orders of magnitude faster, as it just needs to find some common points or prove there are none. So use ST_Intersects by default, unless you really need semantics of ST_Covers or ST_Contains. After ST_Intersects, ST_Covers is the next one in term of performance, and offers clear and useful semantics.
