Which do you think is better?

Which do you think is better,Tekken 4 or Tekken 5?I have been playing Tekken 4 recently.I love the new characters and the movies that take place before and after the battles in Tekken 5,but Tekken 4 is much faster and much easier to beat.There are also a lot of characters that don't return in Tekken 5 in Tekken 4.
