Bitcoin is finite, and Gold is finite.

However, the rate at which they are introduced into the world is very different, which affects scarcity.

As time goes on for Gold, technology advances and getting Gold out of the earth becomes a lot easier. It is not predictable and uncertain.

As time goes on for Bitcoin, there is a decreasing amount introduced due to block rewards being halved. It is predictable and certain.

I know my pick, go with Bitcoin.
