I am able to double dip with C1 Savor and AMEX Plat credit so it looks like a decent deal upfront. I still only do Uber Eats when they have the 40% as the fees are still pretty high and I really have to not want to leave the house to pickup takeout. Without the 40% discount, it is way too expensive to use. I use Uber for rides once a month at best so I like the option to use the AMEX credit for EATS.
