Aluminum vs Fabric Gasket? Which do I use on water pump?

[efine]

I got a seal kit 18-2626 and it came with two face plate to water pump cover gaskets. One is metal and one is fabric. Which one should I use????

Sierra Marine 18-2626 - Seal Kit, 26-43035A4

MOD EDIT - Competitor removed

Is the metal one better? should I put a gasket maker on both sides of it for a better seal?
