Taufik is gifted, and knows which weapon to use in his vast array of shots under different circumstances.
LCW also has many varieties of shots, but his shots are all based on pinpoint accuracy. However, he sometimes does not know which weapon to switch when the situation requires him to change. As an analogy, if your opponent switch to a spear, you cannot continue using your sword. Instead, you should change to use a flail to entangle his long weapon.
LCW cannot go on like this. He needs to stop depending on those few things that he likes to do, like his interception and cross court speed smash. He needs to mix it up a little as you cannot expect to be accurate all the time. TH is good as he knows how to weather a storm, and emerge stronger to beat his opponent after the storm, LD also.
If you watch KKK/TBH, you will see exactly what I mean to be really good and stay on top. They just mix up their play so well, and their opponents are always guessing and trying to keep up. Of course, you can't compare MD and MS in certain aspects, but the keys to victory are similar.
Just my 2 cents.
