I personally like both games. I like Whirlwind a little more. Whirlwinds tend to be a little higher priced. Condition is everything on these since they are system 11 games and both tend to have playfield wear issues. Some Whirlwinds will have a clear coated (Diamond Plate) factory playfield but most will not. ES tend to be in the $1800-$2500 range. WW $2000-3000. +/- depending on condition.
