What comes to mind when I say FPS - Halo or Modern Warfare?

[Gilgamesh]

Seems like the mascot of FPS has alway been Halo ever since it's first release in 2001. But lately Modern Warfare has been making a bigger impact to the FPS world and has taken over as the mascot of FPS. So what comes to mind when I say FPS, Halo or Modern Warfare?
