Quoted from Deez:I think you're going to have owners side for whichever machine they have. I own neither but play both on location pretty frequently. ST has better flow. TWD suffers from cheap drains from dribbles out of the pop bumpers. Rules are cool on both, but could use some enhancements. I give ST the edge due to the lack of cheap drains.
Actually that's exactly how I feel. I like to play both games (ST probably more), but not enough to own either. Tron, XMEN, Spiderman are better games than both.
