Well, if you are throwing away rating data, you are throwing away rating data. They are no longer "100% different" but "100% the same". If that's not a good thing to do, don't do it.
It's possible that using ratings gets better precision, and it's possible that it doesn't. It depends on whether the ratings data are useful or noise, and whether you use them or not.
