1- CJ Graham Part 6 - I think CJ just nailed the part. The aggressiveness and the overall look was great he fit the role perfectly. The tone of part 6 probably added to why i like this version of Jason so much.
2- Kane Hodder Parts 7,8,9,10 (specifically 7) - Kane is just awesome as most of us would agree. He IS Jason, he lives the part and his intensity with the heavy breathing really makes Jason scary as hell. The look of this Jason in part 7 was always my favorite i think the makeup and costume design is amazing yet terrifying.
3- Derek Mears Part 12 (2009) - I know people are mixed on his version of Jason but i personally loved the territorial hunter type Jason that Derek brought to the screen. He showed just the right amount of intensity and body language to show a bad ass killer and at the same time there was a softness there. The makeup and look was also fantastic in the new film especially the sack head version. I would shit my pants if i saw that looking at me in the woods haha.
Ted White Part 4 - Ted White could easily be number 3 on my list i loved his version of Jason in part 4. He was so physically intimidating in that movie.
