what is the best human death in the alien franchise?

I was quite happy when Oram got bumped off. And his chestburster was a real beauty.

I will be glad when Daniels gets eaten by an alien so I don't have to see her anymore ;)

I loved Ledward's back-burster!  Also, pretty cool seeing the Engineers get bombed!

Has to be Ripley for me! What a way to end her arc. I mean, the effects of that shot were just AWFUL, but the emotion overrides that for sure. 

Number two is Dallas' demise. One of the scarier and best crafted scenes in the franchise. Dallas was trying to protect his crew and make up for his letting the creature in earlier, but ended up meeting an unfortunate egg-morphing death!

My number three would have to be Oram's death, I think. It just, it was the first Xeno encounter in the timeline, Oram (a man of faith) birthed a metaphorical demon from the metaphorical Devil, and it was violent as HELL (it frightened me a little). I am in the minority on this, but I thought that the Baby burster was amazing! Weird as hell to see at first, but that design, the music ( I LOVE that piece of the score), and David interacting with it lovingly reminds me how much an icon the Xenomorph is. It really hits home, for me. So definitely a great death scene. 

Kane death definitely. It's iconic.

Actually I like every death in 1979 Alien. :p 

Dillon- went down fighting hand to hand!

Oram's death (a beautiful metaphor), Kane's (iconic), Brett's (Xeno came down like it was nobodys business), Burkes (got his comeuppance), Hudson (went out like a boss), Newt (death of hope), Dillon(FIGHTING SPIRIT), Clemens (was not expecting that), Purvis&Dr.Wren (gave him the best head), Holloway's death (honorable way to go). 

BURKE's demise was entirely satisfying, especially the deleted scene of him cocooned with a chestburster inside him. Ripley showed him little mercy either.

Bishop "death" sort of....

was an excellent juxtaposition for female penetration with Ripley and Queen grappling over the impaled Bishop...that was mighty epic too and symbolic of the typical sexual perversion themes throughout the franchise

Superintendent Andrews'death in Alien 3.

Initially meant to be cocooned...
