jason won because freddy is now in the real world so he can now easily be destroyed and as we all know only a voorhees can kill jason

Freddy won. Suckered Jason into doing exactly what he wanted to do and came back into peoples minds due to this.

Jason. Freddy is powerless in the real world. But like Jason, Freddy can never die. Jason may have won the battle but neither will win the war.

Freddy. That wink at the end means Freddy was doing what Freddy does best, screwing with your mind. Jason thinks he won, and that's just what Freddy wants.

Jason

Jason appeared to have won the battle (for the time being, anyways). But in the final moments of Freddy vs. Jason (2003) ...Freddy appeared to still be alive, even while appearing to be decapitated...I don't think he can die...the same goes for Jason (they're both horror icons)!

Jason. Freddy wasn't thinking about the consequences of bringing Jason back into this world, nor did he anticipate how strong he would be.

It's up to the viewers emotions and feel about the entire aspect of the film, they need to have the characters differences and compare them to before. With the overall expectation of the film and fight value.

Jason Elias Voorhees

Jason

Jason of course, he is the man !

Jason is the victor, of course!!

Freddy

Jason.

My good man the answer is Jason Voorhees

I'd say the studio won, they got all of our money
