As silent/quiet as the grave

Hi.

I'm having trouble with this idiom: "as silent/quiet as the grave". I don't know which one of these two (underlined) words is the appropriate one to use. I tried searching for it on the web, but I've noticed most online dictionaries have it written in both ways.
Still, my English book wants me to pick one. Can you help me? Does it even make that big of a difference?

Does it even make that big of a difference (or: 'that much of a difference')? No.

I would be very happy to change it to something else, but it's the one we use at class, so I'm forced to deal with it. :-)
Thank you. This really cleared things up for me.

We do talk of the silence of the grave, and are much less likely to use the quiet of the grave. In your example, I agree that both forms are fine.
