literally have like 8+ cards but the ones I use the most are amex platinum, citi premier, and apple card
American Express Platinum my main one. Then got a Bank of America Visa too. Then the Amazon credit card. You don’t need more than 2-3 credit cards.

These are garbage, I hate them.
Had the obsidian black card for over a year and the lack of any decent customer service is crazy for that level of money you have with them.
Also, it’s a debit card not a credit card.
But even so, switched all over to an Amex platinum and basically live off of that.
this year been using this chase visa w a 2x cashback bonus at the end of the year. so instead of 1-3% back on everything its 2-6%
gonna pay for christmas w that s***
Amex trifecta
Platinum - flights and hotels (5x points)
Gold - restaurants, food delivery, supermarkets (4x points)
Blue business plus - everything else (2x points)
