Which do you guys think is scarier?

So a friend and I were having a discussion about which zombie apocalypse or virus we would rather live through. I said something about how I would never want to be live in the middle of a Flood outbreak, and he said that the clickers would be way scarier. I disagreed, as while in game, the Flood aren’t as scary as the clickers, but lore wise, they’re a lovecraftian horror. However, while I have played TLOU, I don’t know the full extent of the cordyceps virus.
