Gasquet might be slightly more talented than Ferrer, but I think someone like Ferrer's talent is underrated while Gasquet's is overrated. Gasquet's backhand is probably better I agree, but it is also a highly overrated backhand. Like most one handers, even the very good ones, it has limitations and is consistently vurnerable to pace and depth, and is also vurnerable to effective slice. Like many of the very pretty one handers it is overrated in its effectiveness purely for aesthetics. Ferrer's backhand is more durable and can stand up more easily to any type of shot coming at it, even if it is much less of an outright weapon and has less variety.
Ferrer is a far better mover and defender than Gasquet which is a big part of the game, especialy for two players who are predominantly baseliners (yes Ferrer has some all court skills, but he is still mainly a baseliner).
Ferrer is also a better returner clearly.
And the forehand is not maybe Ferrer, Ferrer's forehand is better by a pretty wide margin. Actually come to think of it I am not even sure if Gasquet is more talented at all, particularly when factoring in the mental side of the game which contrary to what some think is largely something you are born with. Yeah overrated Gasquet and his flashy pretty game with style and Ferrer is not a very good example of this.
