Obviously, ugly is a subjective term. What some people find visually appealing others do not.
I ran across this picture on an akm and it just bothers me. The opposite angle of the two grips would not be quite as bad if they were close to the same size, although their angles make it look like it wouldn't be too uncomfortable gripping it to point in the wrong direction. And the (not so) vertical grip in the front isn't straight. It's curved. But the curve of that grip is completely different from the curve of the magazine. It may be quite functional but it certainly doesn't look good doing it.
