The only plastic model I have, so far, for Malifaux is Snow Storm (that I got 2 days ago). I'm really impressed with the sculpting and it sure was a lot easier to glue it in a pose I liked, versus having to cut, bend, pin the metal ones to get the arms the way I want versus the way the existing pin forces you to put it.
There seem to be more detail on the plastic model than there were on other metal models I have gotten. And since I'm not very good at painting, I am completely dependent on the sculptor to give my paint someplace to sit to make it look good!
