Wouldn't Firefox's profiles accomplish the same thing? (Yes, I understand they are difficult to access but they are still there.)
That said, containers are a handy tool for people who want to access multiple accounts without the trouble of setting up individual profiles. Keep in mind, if you're only trying to access a personal and work Google account you probably don't want to spend time setting up a separate profile for each then keeping the settings synchronized.
