I've edited the comment to clarify, but you're right that they're functionally similar. I was talking mainly in terms of user experience, though. Setting up multiple separate profiles with much the same options and extensions, and then having to actively fire them up for every time you want to use a major site that also employs trackers seems massively inconvenient and redundant to me. With containers, mapping specific sites to specific containers that first time is all you have to do. Containers also share local storage, history, and extensions with the rest of the browser, which is a blessing, as there's no need to install the same set of extensions five different times for as many different profiles, for no added security or privacy benefit whatsoever, and you can access local data in consolidated form, without having to deal with them being fragmented across multiple profiles.
