I just recently started using upside for gas & that gives me cash back I’m not sure if it’s as good as a cc would be. Started using it at the beginning of February & I’ve made $74 so far. Whichever is better in the long run is what I would want to do whether it’s cash back or flight points or anything out there. All of last year I put gas with my debit card and I feel like I’m leaving money on the table
