Those are for different things. I use containers to log in to the same website with different accounts without having to switch browsers or open a new window. E.g., since Discord still doesn't support switching accounts in the year of our lord 2021, I have a container set up for the discord account I use for IRL stuff, and my personal account logged into the "vanilla" container. I can keep both discord tabs open side by side and get notifications from both.

Even for websites that allow switching accounts, I prefer to use containers especially if the accounts go across different "domains" of my life. If I must log in to something personal at work or vice versa, I generally use a container for that to keep them separate.
