User blog:Blur the Hedgehog/Shadow vs Metal Sonic

Now Shadow is my favorite Neutral and Metal is my favorite Villain/Badnik, but my friend is obsessed with Shadow, and I just want to see who is better and have reasons why. (Ex. 'Metal Sonic is better because he was first and is more original' or 'Shadow is better because he is the Ultimate Life form and can glide along the ground.')
