For me I switched from Sam's because I was told the Costco quality was superior than Sam's. 3 things I don't like with Costco, 1 you are forced to only pay with a Visa card. Be it debit or credit it MUST be visa. 2 they do not price match in store their own products with their own online price. 3 you can't use the app for anything other than look at your purchase history. You can't scan items and pay for a faster checkout process, you can't check if the item is available in store, and the price you see on the app might be different than in store so tough luck buy it in the app and wait for delivery.
