Many people talk about the differences between styles and that their style is "better" than all the other styles. I've got say that conversations like this are a waste of time and highlight the immaturity and lack of understanding of the people involved. No one style is better than any other - they all have merit and they all have faults. For the most part combative styles "look and feel" the same - the only differences come from application and "stylistic" variables.
For example, a kickboxer would look at the video below and see how the kicks are used to set up the hands. A boxer would look at the same video and see how the hands are used to finish off the person. A trapping-based (Wing Chun, Silat, etc.) martial artist would see how hand and foot trapping are used to set up the finishing techniques. A JKD practitioner would see how the techniques all work together to create a seamless transition from range to range.
Who's right and who's wrong? It's irrelevant. What they should be looking at is the fact that it works, works well and that the techniques utilized can be from many arts, styles and cultures. In other worlds, there is a "universality of truth in movement" that could be from any combative style and the reason that the technique is in so many styles is because it works.
