When the first pics of MOM Wanda were revealed, I was let down because I really liked the bare shouldered WV version. The poofier hair as well. But apart from the MOM version representing the Wanda I enjoyed more purely as a character, looking at the two figures together, it puts things into perspective. The truth is, the WV is just too techy for me. The same material, the same Y-esque shape that makes every single MCU costume look identical and most of the time, bland. Random lines, random geometrical shapes that look like chips; it's a generic MCU "sci-fi" costume that could belong to any superhero with any kind of powers. Not to mention that in the figure the bare shoulders don't work and make her look more toy-like.
In contrast the MOM version looks properly witch-y and the sleeves maintain the illusion. The muted colours hide the generic MCU aspect of the costume, and the lack of an awkward cape sell it better. The tiara missing the fill-in black pieces makes it look like devil's horns too in a way, beyond being headgear. The torn waistcape adds to the flair.
I think there are things to like in both looks, and technically Wanda at her cabin was the best she looked:
But the figure lacks the poofy hair, and in that gif all the glowy aspects are obscured by the lightning, whereas in the figure they're visible, making the trite MCU pattern stick out all the more. In the MOM figure everything's more subdued and with some good posing you definitely get the vibe of an actual Demonic Scarlet Witch here. The colours, the flair, the look, they're there. If it were up to me I'd have made some more changes, but the simpler colouring pair of deep scarlet + black, as opposed to all the light red/pink/scarlet/black/grey/metal combinations of the WV version, works much better.
For my money, I'm glad I waited. In theory I could wait more and get a "perfect" one (hopefully with a proper Witch-y costume similar to her current comic look) but I did both enjoy her role in MOM and this technically being an evil/posessed version, means I can double dip and not feel as if I'm getting doubles. Some characters I can justify that due to the displays I want to set up.
