>>6288313Mafex was my #1 Vader for a long time, but after getting the new black series I realise he's just too skinny and his head/face is too small. The extra articulation is nice but I don't really feel it's necessary for a character like Vader. I miss the extra hand options but overall I'm happier with the beefier looking black series on my shelf.
That being said, the Mafex Vader is pretty cheap compared to the new BS so it depends on how much you want to spend and what you want from the figure.
