default(Quaternion) is not equal to itself when using equality operator
Quaternion defaultQuat = default(Quaternion);
Debug.Log(defaultQuat == default(Quaternion));
// always false
float defaultFloat = default(float);
Debug.Log(defaultFloat == default(float));
// always true
Quaternion defaultQuatTwo = default(Quaternion);
Debug.Log(defaultQuatTwo.Equals(default(Quaternion)));
// always true

I don't know much about the math involved and how exactly this causes that behavior, but:
Equals method checks the x,y,z,w values to return a result while the == operator checks for their dot products.
default() returns zero for value types.
but (x,y,z,w)=(0f,0f,0f,0f) is invalid value for quaternion.
their dot products is zero. so, == operator(checks dot products close to 1f) returns false.
if default(Quaternion) will be (0f,0f,0f,1f) then == operator will be true;
