It depends. Hastings is in San Francisco, much better for networking if you are trying to work for top 10 SF, Palo Alto etc firms. More alums in private firms also. Davis is good for public law, clerking in Sacramento etc.
Oh yeah, Hastings median private sector salary is bananas--as high as top 20's like Boalt. I also chose Hastings over Davis, before I got into G-town. Check my post on 1rst page and weigh in--Hastings vs Georgetown PT, I must decide by Friday.
