I was always someone who checked which card to use thoroughly -- too much in fact. But now with OneCard, I haven't checked anything in a while. But my credit utilization rate has never been better. I think my score went up ~20 points so far.
OneCard is really amazing. I decided to go with the completely digital version, using it with ApplePay. Haven't used my other cards since, might even send them back!
As one of the first users of the card, I was genuinely blow away. I upgraded to the founders edition card and its like throwing around a black Amex. Can't stop showing it off!
