Use Citi AA Exec or Amex Blue Cash for AA EXP?

This year, I have spent close to $40,000 on my Citi Executive® / AAdvantage® World EliteTM MasterCard® to get the 10,000 EQM. Here were the reasons why I signed up for this card:

• 100,000 bonus miles (who wouldn’t?)
• Admirals Club membership (to replace the American Express Platinum Card)
• 10,000 EQM after $40,000 spend in a year

The Admirals Club membership is a real treat. I love going to the lounge before and after a flight to get a quick snack, orange juice and some coffee. It’s also a great place to kill some time before my flight and also to help put me on standby for an earlier flight.

I recently got the American Express Blue Cash credit card (old version) for the 5% cash back at supermarkets. So which one is better if I had to spend $40,000 at a supermarket next year? (I run a lot so I eat a lot. Sue me)
You can get the card here (and no its not an affiliate link) (and Yes George, that line was for you): https://www304.americanexpress.com/credit-card/blue-cash/
Bonus category details: Up to 5% Cash Back at U.S. supermarkets, U.S. gas stations & select U.S. drugstores (Everyday Purchases). Up to 1% Cash Back on other purchases. For your first $6,500 in purchases in a reward year, you will earn 1% on Everyday Purchases (5% thereafter), and 0.5% on other purchases (then 1%).

When you spend $40,000 with the Citi Executive® / AAdvantage® World EliteTM MasterCard®:

• 40,000 AA miles
• 10,000 EQM (worth roughly about $500 based on mileage runs at 5CPM)

When you spend $40,000 with the American Express Blue Cash at a supermarket (considering you met the 5% cash back spend threshold before the $40,000):

• $40,000 x 0.05 = $2000 Cash back

Is it pretty clear which one I would be going with next year?
