Both are metamophic Rock. Gneiss is formed from Granite. Schist from other types it depends on what you are planning on drilling. Also it depends on what type of Schist. Gneiss would probably be the better choice though.
What mineral is common in schist and gneiss but not common is slate and phyllite?
