Chrome supports multiple profiles. Mozilla's Multi-Account Container tabs isn't multiple profits. It is multiple isolated containers running under the same profile, in the same browser window.
A closer analogy would be if Chrome allowed each tab to have its own profile, rather than each window, and for each one to be lighter weight than a full profile.
With Chrome, even if you manually sync your profiles and keep the same set of extensions installed in both profiles, it runs 2 processes of the same extension. Even when the second profile window is closed.
But for me the deal breaker was managing a separate set of bookmarks.

“They're also great for development. I have different containers for each user I use while working on logged-in flows. I can just go from tab to tab to test different user experiences or switch between users in a multi-user interaction.”
