Noise from Solid Engine Mounts?

Just wondering if anybody around here has experience with solid steel engine mounts as opposed to rubber ones. Need to replace the mounts for my 318 (as they disintegrated in my hand when i removed them) and was wondering what people use and the advantages and disadvantages between rubber vs steel ones. I feel like I like the idea of steel ones but am really wondering how much more noise it'll make in the cabin. Any help would be greatly appreciated. Thanks!
