Are there any credit cards that are sleeper? Tell me what your secrets are

Anyone have any sleeper credit cards out there that are huge hitters but are relatively unknown? So, for example, the pnc cash rewards visa I have (my first card) earns 4% on petrol, 3% on dining, 2% on grocery, and 1% on everything else. It’s a nice gas card for me because it has an annual ceiling of $8,000 on the 2,3,4% categories. I recently learned about the Red Stone Federal Credit Union card, and it appears to be a sleeper. Yes, it has some caps on it, but it appears to be a beautiful card even without them. Does anyone have any additional lesser-known ones?

While there’s no perfect solution, thorough research can help you discover a credit card that provides excellent value based on your spending habits.
