Napa Vs Walnut Creek

Hello gang, this is my first reddit post so please excuse me if I should've posted this elsewhere.

I am moving this year to either Napa or Walnut Creek. Both equal commute to my place of work. Looking for overall pros and cons of the two areas as I have been an east coast guy most of my life. I have no idea how the vibes of the two areas differ and what either has to offer other than some google searching I have done.

Background on me to help narrow recommendations: 28 year old male, single, looking to be in a walkable area. Looking for apartment recs also, so please feel free to share. Thank you!
