Chaos Series?

[P_Clapham]

I've got some questions regarding the Chaos line of skirmish games from West Wind.

First off how close does it come to playing like the Supersystem?  I noticed in the quick play that when you roll sixes you get two goals instead of one.  Also it seemed like they don't use the Supersystems action points, the sample gents just have their base moves and an attack listed...

Is there a significant difference between the Chaos in Cairo Rules vs the newer Chaos in Carpathia Rules?  In the downloads it did seem like there was a slight difference.

Lastly do you enjoy the ruleset?  Is one better than the other?
