Soft plastic is not the issue I'd say, they use that kind of plastic on many things today. Like Jeanne's ponytail piece, Vice's tail or the body on Seihou OG Ultraman. This stuff is fine, feels pretty nice in-hand too. Just the right amount of give and flex. Especially on Ultraman it adds a lot to the feel IMO, don't know how to describe it properly, it feels more like a real suit in my hand and not a hard plastic figure.

Tiga and Black used rubber IIRC, that's a whole different story.
