Which speaker system is the best?
It all depends on what budget you have. There are cheaper systems that maintain a relatively good level and that take your movie-watching experience to a new level if you have previously only used the TV's built-in speakers. However, the more expensive packages are of higher quality and create a larger and heavier sound experience, more similar to the one you can experience at the cinema. In short, the more speakers and more powerful amplifiers, the better sound you get.
