For Gaussian blur, pretty is irrelevant, and just trying to figure things out, pretty is also irrelevant but... if creating "lens blur/bokeh", it's completely useless if the bokeh is ugly - because that is what bokeh is about... "the aesthetic quality of out of focus elements from a lens". I can create examples from a real camera to demonstrate the difference if that helps in the future.
However, I misread the original post where they were just wanting to be able to do blur period, which has plenty of value on it's own. Not trying to be overly pedantic, it's just the difference between the two matters a bit.
