Depending on the order in which you perform these, you will end up with different final orientations.
So proper rotation coordinate systems are needed.

One advantage of this mode is that animation curves are easy to understand and edit.
However, special attention must be done when the middle axis approaches values close to 90° (or equivalent angles).

The axis-angle system is free from gimbal lock, but animation curves in this mode are not intuitive at all
