Precession refers to a gradual change in the direction of Earth's axis of rotation.
Precession of the equinox.
The Earth is a spinning top (gyro) with a different moment of inertia about the spin axis than the other two axis. Therefore, it acts like a spinning top with both precession and nutation. Precession of the polar axis (relative to a 'fixed' distant star) forms a cone. The precession period (~26,000years) is the time it takes for the cone to be traced. Nutation occurs normal to the precession cone and has a much faster period (~18.6yrs).
Earth's axis wobbles.
The Earth doesn't wobble around its rotation axis. The rotation axis itself rotates,so that the Earth's poles trace around a 23.5-degree circle in the sky, every 26,000years. The term that describes it is "precession".The Earth doesn't wobble around its rotation axis.

1- it is amatter of preference 2- considered under gyroscopic precession

The principle of gyroscopic precession is responsible for the actions of a boomerang in flight. The torque resulting from the aerodynamic lift of the moving object causes a curved axis, and the subsequent path of return.
The plane in which the reactive gyroscipic couple acts is called the gyroscopic plane
principle of gyroscopic couple ? how gyroscopic coule work in a aroplanes & ship ?
If the precessionnal motion is caused by applying gravitational torque,it is called gyroscopic motion.

Precession, which in this case refers to a movement of Earth's axis. A full "turn" takes about 26,000 years.
