Sod. Much quicker to the end result and just easier IMO, particularly with how dry it is here.
Make sure you have a good sprinkler setup, including a good timer with settings to accomodate new seed/sod (love my Rachio 3 smart timer BTW).
Prep is extremely important:
I use Fiske Brothers Yardworks for the aeration and fertilization schedule. They let me know when it's time so I don't have to worry about it. I just water it and mow it.
