Can somebody compare scanner sound?

From what I'm reading in these posts most prefer the GRE to Bearcat for P25 because of decoding. My experience with RS analog scanners is some terrible floor noise. I can have stations a mile away with fantastic RF levels and there's always this shshshshshshshs going on in the background. My ham radio sounds beautiful with no noise; it's like they are sitting next to me. Also is a Pro197 identical to the GRE?
