OAK and LAS are definitely your best choices.
I really like Las Vegas. There's always something fun to do. It has the best food and entertainment in the country, tons of outdoor activities, the weather is great, cost of living is cheap, people always come to visit you, you can fly nonstop to anywhere in the country. You're very close to LA, SD, Phoenix.
The Bay Area is a great place to live too. It's beautiful. You're near the ocean. Tons of outdoor activities. Great culture. Mild weather. Only draw back is cost of living.
