>>9492388C6 zaku has a few different parts that can be used. Different left shoulder, different plates for the chest. Colors are pretty much the same for the c5 and c6 zaku 2. The new updated hguc zaku is probably the better way to go if you want something looking closer to the anime versions. Both are nearly identical in articulation but the revive has a little better articulation but not by much. C5 zaku has a few different weapons like the antiship cannon, but the revive just has the mg and bazooka and heat hawk. U think the c5/6 doesnt have the drum mag mg but just the belt fed mg.
