First of all, I should like to withdraw my comment that an image that is rotated using "set the angle" is better than one using "rotate".
Here is an updated stack; pairs of images are produced: the one on the right is rotated using "set the angle", the one on the left is rotated using "rotate":
it can be seen quite clearly that the one rotated using "rotate" is far crisper than the other one.
