Both are equal to me. I buy golds with bitcoin earnings. Though these prices fluctuate, though these two have same values, they differ in few scenarios. Gold is a physical coin and Bitcoin is a digital currency. Gold at times are stolen outside. Compared to gold, bitcoin is more safe though it is sometimes hacked from few users who have not yet set security in their systems.
Both have similarities in the features that they offer, but they are not the same.
One of the important differences is that you can use Gold as currency tool in offline transactions, where you with Bitcoin need to be connected to the internet.
Gold is also a favorite option because it is a great hedge against their local fiat currencies in the time the economy is going from bad to worse.
Bitcoin is secure in the way that you can either store it on a piece of paper, or your wallet files in a USB drive, compared to Gold being in a large physical form when hodling large amounts. Is that what you mean?
