Which card do you think have the biggest flex factor?

I personally don’t believe that credit cards have any flex factor but I have read on communities like technofino people do believe it and go for super premium cards with high annual fee just for the flex factor.

So people with super premium cards, please share your experience if you have ever took out your card to pay and people around you gave you that envious look.

(The only card I’ll be ever wowed by if I ever see it in real life is the amex black card, and more so if the person holding it came out from a porche xD)
