Forum:Who would win in a duel? Yugi, Jaden, Yusei or Yuma

I was wondering who do you think is the stronger duelist of the four? Yami Yugi is really strong duelist. And Jaden is not strong (without supreme king and Yubel's power). Yusei is too strong duelist, he use invincible strategy. Finally, Yuma is total useless duelist, but when he fuse with Astral, he can activate zexal power. For him what is your comment about this?
