The Gasmask Zombies from The Empty Child and following Doctor Who episode. Loosely a dozen of them

vs

The Traditional Zombies of the recent Dawn of the Dead. Loosely three dozen of them.

EDIT: Slightly clearer scenario

Gasmasks win, all they need is a touch, and the kid was very powerful and the nanobots kept regenerating him, it's unlikely that you could kill him without blasting him into small gibbets

Given the Nanogenes become airborne before it's reset, the gasmasks utterly rape the traditional zombies. They brought the kid from fatally wounded to Zombie to healthy human. Hell, they regenerated a leg.
