The Lizard

Not sure about the other lizard, but I can tell you that I prefer the Walmart ASM movie Lizard over the Select Lizard. Aside from Select Lizard's head being oddly shaped, the articulation on the ASM movie Lizard is outrageous. At full height, he seems to stand taller than Walmart Avengers Hulk! The head/neck deal is strange, though. It kind of slides back and forth, and if you have him all the way back, there's a noticeable notch (where the head slides) visible that makes it look weird. Other than that, its a cool figure. Select isn't too shabby either, I'd say like most select figure, more goes into the detail rather than the articulation. So really, will you be displaying or using? Select for display, ASM movie for use.

I'm not interested in MS Spidey though, if only for the fact that I focus mainly on 6-inch figures, with some exceptions.

I personally prefer the MS figs, the Spiderman is perfect! The Lizard is pretty cool too. His head is just a tad to big. Hope that helps.
