Best Sunset view: Berkeley Hills overlooking SF bay. Fort Point overlooking the Golden Gate bridge or take a cruise around Alcatraz around 7 pm for a stunning SF sunset. If you are in LA area, take a drive on PCH or stop by Will Rogers beach in Malibu, the sunset in Malibu is spectacular, too. Or go to Griffith Observatory, best view of the entire Los Angeles area. In OC, I love Newport Beach and Huntington Beach, surf city sunset view here....gorgeous. My vote go to San Francisco. I sort of missed the scenic SF views now that I left, the place, apt, living condition...not so much.
I am not much of a morning person, never really seen a Sunrise view.
