I have 4 Microsoft accounts I use regularly for work. I also do some consulting and often end up with credentials provisioned at a client (don't get me started on this). It is so convenient to have container tabs. All my extensions are available in new containers, unlike multiple Chromium profiles (or Firefox profiles). Container tabs also pair very well with Simple Tab Groups, which allow you to pin a container to a group, so that everything for one account ends up in one place.
