Best camera for the job i suppose. If i need something professional i will deck out the Pocket 4K with whatever i require for that project (follow focus, gimbal, etc) i enjoy modularity and the fact that this camera starts off small and can be built up to your needs), if i'm on a family vacation and want to travel light while running after my kids then i'll go for convenience (IBIS, Autofocus). I don't think iPhones are up to the quality standards we are looking for as of yet.
