I got the Previews exclusive yesterday (my favorite of the available color schemes), and it really is a nifty little figure. I would actually rank the relative quality as higher than that of some SSC 1/6 scale figures. The light blue looks better in-hand than in the pics I've seen somehow. The articulation could be better, but it isn't bad, and it might be best to have some limits here, given potential damage to the suit if he were placed in poses that were too extreme. My other major niggle would probably be paintwork on the faces. They are OK, fine for the price point in fact, but they seem on par with mass produced 6" toys. One of my concerns based on pics online was the cape, but it was a lot better in-hand. I think one of the issues is that with most pics I've seen, people haven't futzed the capes to hide the edges where they are cut from the bolt. It looks a bit uneven, as you can see in the post above, but it's easy to hide this by folding the cape back, similar to some of the custom Dark Knight Hot Toys capes we've seen over the years.
A nice figure overall. I won't get going all out with this scale/line, but will likely pick up other characters that I have a particular interest in. I would particularly be interested in more classic Marvel and DC comic characters.
