Now I just use my apple card everywhere, pay it off every month and get whatever rewards I get.
It feels like a weird situation, those that stand to gain the most from credit cards are also the ones that should feel a difference of under $100 in rewards the least.
The one exception I see is bonus sign up rewards since those can be fairly significant, or making sure you use an airline card at the airline since those bonuses can be fairly significant (with sometimes other benefits). But outside of those exceptions, just choose a card with good rewards and stick with that and pay it off every month.
