When shopping for houses in Sacramento as a first-time buyer, which zip code is preferred?

I got a call from a potential buyer the other day wanting to look at houses that she had picked from the MLS herself (I love it when buyers are involved in the process from the start and don’t wait for Realtors® to do the research) and the two themes I saw repeating were 95608 and 95821. Personally, I like 95821 because there are some pretty great deals out there for first-time buyers. But my client has never lived in Sacramento, so I want to really make her feel at home. Any ideas?
