Erak,
Never had a chance to play WH2O yet, but you seem to have similar tastes as I do (Evil Dead, MSF). My Dredd had been great to me as far as no problems, and the gameplay is challenging and deep. Hidden easter eggs in the DMD scenes that are funny (how you would ever find them without being told I don't know), and the artwork on the machine is great.
I'm hoping to play WW next weekend at a show in Cuyahoga Falls Oh., as it looks like a real fun game. I can compare the two after that.
