Questions about Rotations in unity

what exactly is the difference between Quaternion.EulerAngles and transform.EulerAngles. I know that using Quaternion avoids Gimble Lock, but their both referring to the same t$$anonymous$$ng so wouldnt they have the same values? Also, im a little confused as to how localEulerAngles would differ from regular eulerAngles. I know that local means its rotating relative to the parent, and i understand that completely with changing the position. but ive seen rotations do weird t$$anonymous$$ngs in unity with skewing the object so rotation wise, what exactly would be the difference in the result?
