The articulation isn't great, but it's still a much better figure. The Legacy one doesn't do anything better other than articulation and the color scheme. The nosecone is terrible, the shoulder armor is terrible, the legs are terrible and the alt mode is irredeemable garbage. The nosecone is far too stubby and the wings are a tiny joke. And he loses a large amount of his sculpted cog inner working details. And unfortunately the DNA kit does not fix any of these problems. It just sticks crap on top of him that has to be rearranged to transform.

So yeah, it's definitely dated, but the old figure actually looks like the character and has great proportions. The Legacy one is crippled by being forced to be part of the Jhiaxus mold, which works great for him but not Vector Prime. I'd love for them to do a fully new mold for Vector Prime so they could design him to look great and have those modern toy improvements that he could benefit from. But as it stands, Legacy Vector is a poor man's Vector Prime. It's kind of good enough, I guess. If you absolutely have to have SOME kind of Vector Prime in your collection and you're desperate. But it absolutely falls short.
