I’m switching over to the Aven rewards card (Flyertalk thread) which is unlimited 3% cash back on all purchases.

Unlike the Robinhood Gold Card, you don’t need to pay for a membership, and it doesn’t exclude tax or other types of purchases from cash back earn.

But there’s also other offers (really different “flavors” of the same card): 6% back on groceries up to $10K/year and 2% everything else, 6% back on gas up to $10K/year and 2% everything else, up to 10% on all purchases in a tiered system for referrals (see thread for details).
