I think Crystal wins for sure. Shaggy never showed any signs of really being crazy for Google. Also, this is just an opinion but Google's kinda a pointless character and added nothing to the movie. On the other hand, Shaggy was so in love with Crystal that he broke out into song! Crystal also had a little companion for Scooby as well- Amber! Honestly, I don't think there's any competition. Crystal wins hands down.
