That's not ALWAYS the best way - you should see the value in both if you're a JKD student. The thing is, even though you may be able to put a guy down in less punches with a more "powerful" strike, it doesn't mean you will. Too many MAists overlook the fact that it is not easy to knock someone out, no matter how strong you are. Personally, I like faster punches and multiple targets. Sometimes it's best to break the branches before you fell the tree.
