For simple cashback without yearly fees, 2% on everything or 5% on some things is about as good as it gets. I do everything on chase for simplicity and I’ve been reasonably happy with them. Twice now they have detected someone trying to use my credit card number (not sure how they got it), stopped it, and alerted me instantly. I mostly use the freedom unlimited card which was one of the better cards when I got it a few years ago.
