Depends upon what you are using the gyro to measure. For an attitude indicator the spin axis is vertical. For a turn indicator the spin axis is usually horizontal, ie across the aircraft.

Nice diagrams here:

Gyroscopic Instruments - Flight Instructor Wiki

It shows turn coordinator gyro is canted diagonally, so it can respond to both roll and yaw.
