>>8704466Ehh, those aren't like, terrible kits or anything, but they are very, very outdated. You'd be better off individually buying more modern incarnations of both, like for instance the Revives, or the Origin versions. They will have substantially improved engineering. For an example, here is the Origin Zaku on the left, and the original HGUC (which is what you're getting in that box) on the right.
The only reason I'd say to get that box is if you really like the old-school proportions with longer torsos and larger heads.
