>>5777304nendo has more extra parts and faces, and the size makes it ideal for interacting with other figures, but his feet are too small and round, so making convincing kicking poses is hard, let alone making him stand on his own, even with the little stand plug.
the old takara toy has bigger and flat feet though, so he can stand with no problems, but he looks too big for what it is compared to other figures, no hole for stands so airbone poses are almost imposible, and you need the other two kirby sets to get more expressions, which are hard to find, and when you do, oh dear god those fucking prices.
overall the nendo kirby wins for me, and compared to the takara one, he's cheaper and has more stuff
