UX wise, 100%. Switching between the main profiles is more like restarting your phone in new profile, and then restarting it back.
With the Island, you just have 2 custom sets of apps (personal/work) accessible at your finger tips.
- can open both at once
- copy paste text from one to another
- share files/pictures in between them, ...

The setup and onboarding is little cumbersome, but afterwards, the UX is solid. *The file sharing kinda sucks until you get used to it and develop some system.
I pretty much have the work profile w/ GPS just for the Google Camera and the fiat banking apps.
One thing I'm unsure though, whether I'm getting any real privacy/security benefits like this vs having the GPS installed and enabled just for some of the necessary apps.
