I have the personal American Express Gold Card. It can have advantages given that it is a charge card. But it is no longer offered by Amex.
I guess I keep it for sentimental reasons, and laziness, given that I've had it since 1982. It offers one point per $ on any spend I do, though I have not done any government spend on this card. It also offers ability to transfer points to various airlines other than Qantas. In the main I use the Qantas American Express Premium Card, for which I get a discounted fee given I have the Gold Card.
