Gasquet has great feel and touch but failed to develop even a top 30 level forehand. There's no way he can win big events with such a glaring weakness in the most important aspect of the modern game.
Berdych has one of the best forehands and one of the best backhands on tour. He's an amazingly clean ball striker on both wings, kind of like a more powerful Agassi with a huge serve. IMO he should have won several majors at least. It's no contest who is more talented IMO, especially for the purposes of the modern game.
