User blog comment:Helix Armada/Which Killstreak system was better, the one in COD4/WAW (3 set killstreaks) or MW2 (customizable killstreaks)?/@comment-2072048-20100920224706

I liked them both...as price said, you can pick what suits you, but set are fun too, as you already know when things are coming up, and you don't need to worry about tubers get MASSIVE high KS.
