Gold in general is no better. The value of gold is nothing more than a result of a global consensus - at the moment everyone agrees to consider gold a measure of value, simply because this measure is in some form or another necessary. If we assume a utopian situation, that tomorrow everyone agrees that gold is not such a measure, then it will be good only for the production of quality wires and trinkets.
The btc is gaining momentum for exactly the same reason - the global consensus towards the btc is constantly being strengthened. In this case, unlike gold, the cue-ball is not only a measure of value, but also a settlement system, and gold is not a competitor for this parameter.
You have good point, only the gold is physical. And this more appealing to people since they trust something that they can see or touch, understand not some kind of mystical digital currency.
Not to mention that Gold also could be a bubble because there is more gold bought and sold in exchanges than there have been ever mined.
