Not across the board which is why many people possess multiple cards and use each accordingly depending on the purchase scenario.
BofA Cash Rewards Visa gives the cardholder to specify a category for 3% cash back. I selected Restaurants/Dining since it's probably my largest single discretionary purchase budget line item. Plus, many U.S. restaurants (especially the nicer places) do not use Apple Pay for diner transactions anyhow.
AMEX Blue Cash gives 3% cash back at supermarkets.
Chase Rewards Visa gives 5% on a rotating category every quarter. Right now it is gas stations. It appears to be for everything purchased at a gas station (not just gasoline). I just paid for a BlueRhino propane tank refill at a nearby gas station.
For almost all other U.S. domestic purchases, I use my brokerage firm's Visa. They offer 2% cash back on all transactions, regardless of merchant and regardless of transaction type (swipe, Apple Pay, card not present).
For big ticket items plus U.S. domestic travel, I use AMEX. They offer new purchase protection, extended warranties, travel related insurance/services, plus I still get 1% back.
I have a couple of periodic transactions that use overseas payment processors (these are card not present transactions), so for those I use a Capital One VentureOne card that has no foreign transaction fees and 1.25% cash back.
Using your Apple Card to fund iTunes Store/App Store purchases for 3% cash back is stupid. There are periodic iTunes gift card sales at 15% off; one just concluded at eBay (it was announced here at MacRumors). I paid for the discounted $100 card with my brokerage Visa and I got net 16.7% off (15% up-front discount + 2% cash back off the $85 purchase): for a $100 gift card I paid $83.30 net.
Thus, the three cards I usually keep in my wallet when I'm at home in the U.S.A. are the BofA Visa (3% restaurants), AMEX (3% supermarkets) and brokerage Visa (2% all transactions). All of them are in Apple Pay.
None of my cards have an annual fee and I don't carry balances either. My credit score is currently 817.
Anyone who says you should carry a small balance from month to month doesn't know what they are talking about. There is probably more misinformation in Internet discussions about personal finance than pretty much any other topic.
