Just to amplify on Leon's comment about why it sounds so good: as he hints at, it is indeed the same reason the golden ratio is a good rule of thumb to use when choosing the length and width of a room for recording. The primary reflections in a golden ratio room do not coincide, so you avoid the build up of resonances and instead get a pleasing diffusion of echoes. (there are improvements you can make on the golden ratio, but it is still a good rule of thumb.)
It's the same principle with delay effects. Echoes that coincide tend to make the delay effect less pleasing than if they are diffuse. So if you want a lush David Gilmour sound, stay away from ratios that are related by integer pairs (25%, 33%, 50%, 67%, 75%, etc.) and instead use the golden ratio .
