re: Business credit card rewards, best card ?

I get the phone credit (it’s monthly) and just used the CLEAR credit. Already had Global Entry. It’s hard to use the airline credit as it’s only for purchases outside of tickets and I rarely check a bag. Got a nice Garmin watch with Dell credit. Looking at maybe a backpack or noise cancelling headphones next on Dell but I can definitely see how you would run out of things to buy on the site. The Centurion access is definitely the nicest perk. I’m going to NYC soon and might try the Platinum concierge service.
