The body styling from the Medi looks better for Maul, much thinner and much more like I remember him from TPM. The neck is really distracting and throws off a good headsculpt enough to have me not buy it (enough though I didn't anyway). The poses that I've seen and sure will see will definitely make use of the RAH body but the hands are too large to look natural another unfortunate production casuality. I don't like the thin sabers either. Both SSC's Maul and Medi's Maul have their flaws...looks wise if you get past the neck Medi's Maul looks more like him but overall I'm gonna stick with my SSC.
I could live with the minor flaws that Medi Maul has,but really can't live with the huge flaws SS Maul has IMO.
