User blog comment:Legionwrex/Spectre vs Spartan II/@comment-217683-20100909221913

It's not really a valid question. The reason I say this is because Spartan-IIs are all put through the same very rigorous training. They are a military unit, and as such are subject to uniform training and are equipped by the UNSC, and they are solely a combat organization.

Spectres, on the other hand, are not a uniform entity like the Spartan-IIs. There is no Spectre training that they all go through. They don't all receive the same top of the line equipment from the Council. They have to buy their own. And they don't all have the same mission. Some Spectres are pure diplomats, while others are pure fighters. It's like asking who would win: A Navy SEAL or a Soviet solder. Well... what kind of Soviet soldier? They aren't all the same.

So asking who would win, a Spectre or a Spartan-II isn't a valid question. You'd need to ask about a particular Spectre, since there is so much variety between Spectres. Spectre vs Spartan-II = not valid. A Spartan-II vs Saren, on the other hand (or Nihlus, or Shepard, or Tela Vasir) would be valid.
