It is certainly not perfect but it certainly way faster and seamless than rebooting into another OS.

If you don't mind the battery drain and having both profiles running it is just a menu drop down + single button and ~1 second wait and you have your other profile.

Personally I hate the battery drain so the process for me is a menu drop + single button and ~3 second wait and then unlock pin and I am in my other profile (not ideal, but far better than anything else if you want degoogled).

You can even get notifications from other user profile(s). This is absolutely impossible with dual boot.
