Palm Springs and Scottsdale are magnitudes hotter than LA. When I used to live in Scottsdale, every day between early May and end of September will be above 100. LA weather barely gets into the 90s. Most days it is between 75-85. Also, Palm Springs and Scottsdale do not have beaches, do not have nearly the same level of entertainment (music venues, clubs, bars, nightlife, two football teams, two basketball teams, stories baseball teams). Not to mention access to nature, wine countries, international airports etc. I lived in LA for 2 years, even with all its traffic problems, it is a 10x more interesting place to live than Scottsdale
