Similar! The biggest difference in my mind is that any website using FLoC would be able to know what cohort I belonged to.
FLoC is definitely more anonymous than "davidlumley visited nytimes.com twice on December 1st 2022". However, that particular usage information was previously only available to nytimes.com, any ad/data vendor using third party tracking cookies that were present on nytimes.com at the time of my visit, and finally any company that purchased data from the ad/data vendor.
My FLoC was theoretically available to any website and had much of the same intent data that intent ad/data vendors were/are selling.
If my understanding of Apple's ad platform is correct, advertisers don't know which cohort the user davidlumley belongs to, or that their ads are being served to me because that's all handled on device.
