Alien for me as the incredible amount of source material to draw from should provide for quite a rich intense atmosphere in the Heighway pin. I enjoyed the Ghostbusters movies but anytime I hear the theme music it still makes me cringe. Can't imagine having that hit me in the face every time I turn on the pin if it were in my home environment. Shudder... 
If the two pins did indeed come out at the same time and cost the same, how do you quantify the exchangeable playfield/art system built into one and not the other? When taken into account it kind of makes for an unfair comparison.
I could go for a modern wide body pin with all this going on in it...
