it's just my opinion and from not owning any Yamato 1/48 that the Yamato stuff may have better detail but the build quality and mechanics aren't as good as Bandai 1/48 scale stuff. I could be wrong but I mean if I'm looking for a more rigid transformable product that possibly is resistant to yellowing I would go with a 1/48 from Bandai. I only own the smaller scale Yamato stuff, the whole set in V1 only none of the perfect transformation ones. One of my valkyries, the only one I ever unboxed, has bad yellowing. One day I'm going to shoot primer over the whole thing and re-paint it. I'm fairly disappointed with Yamato quality. But again that is just my opinion.
