Yeah, I've used both and the SAMONAS is higher quality. It is also easier to listen to repeatedly because the tracks contain audiophile-quality classical music, as opposed to the endless sound of a rushing stream.
Keep in mind, though, that the quality difference will only become apparent if you are using quality (at least $50) headphones and a reasonably good stereo. If you listen on cheap equipment, the quality will be effectively the same.
