Just opinions, I think the KS blows this out of the water. The torso twist was Todd being Todd, but that figure is a dedicated sculpt with incredible paint. I don't hold up soft goods like others do so don't see this new one as an upgrade persay. Also, the KS was less than this one will cost. I know the time value of money has sway here, but still.
Of course, just opinions here: Dedicated sculpt is only a good thing if it's a good sculpt. But the KS figure had hideous wrists, those stupid feet, and was designed specifically to not look good in most poses you might want to do with a Spawn figure, or not even be capable of doing them. So the dedicated sculpt isn't really a positive. It's just a thing that it has.
I'm not sure what reason there is to believe the paint on the KS will be any/much better than this figure. After all, it's basically the same design and color scheme. It's not exactly hyper-detailed like, say, the medieval Spawn KS figure.
Even if you're ambivalent about softgoods, the plastic shell cape, while a nice homage to the vintage toy, only further renders the figure practically immobile. If nothing else, the new figure should at least be able to be posed in, you know.. Spawn poses.
For price -- that is certainly going to be dictated by where you live and how it's made available. If I can find this thing at GameStop or at an e-tailer I frequently use, I guarantee it will be cheaper for me than the KS figure was. After shipping, that thing was like 100 CAD for just the regular unsigned version.
I like the KS Spawn, despite what I view as its faults. I don't know if I'll even bother to pick up this new one, and if I do I probably wouldn't get rid of the KS version. So I don't mean this to just bag on the KS figure. But I would definitely see this as a sideways step, not a downgrade. And more importantly, this figure is basically what the KS backers were asking for, which is where I think we might see some frustration from collectors.
