I'm not an expert on of any sorts. But these cashback values are much better than my current credit card. And I pay an $100 a year fee for mine. This one is free. It just seems a very solid card.
I'll wait for the Lyft one though.
The page is misleading — those percentages aren't cash back values, they're for if you redeem as Uber credits; only 1% if you redeem as cash back.
For any online purchases, I suppose that's less of an issue.
