Would it be scarier if the revolution was by tons of tiny robots, or a few big ones?

Watch this video (saw on Gizmodo) that shows “Swarmbots” communicating and organizing to execute a (creepy) task. I don’t know why watching this swarm of robots slowly overtake a little girl is so disconcerting to me. Just watching them come into frame is like a horror movie.

Would you be more afraid if the robot uprising was by tons of these little robots, or by a few high-powered japanese super robots?
