I have always admired Apple for their user-friendly and clean UI design. It is easy to navigate, not overwhelming to the eye, and very customizable. They put the power in the user's hand to personalize their workspace to best fit their daily needs. Users can pick which functions to include in their control center, which notifications show up and when, and also which apps to display on their home screen without actually deleting anything. Their UI can be very personal but while still staying true to the Apple brand, and it has Apple fans like me always anticipating their next update!
