I am faced with a tough choice between these two schools… I’ll keep it simple…
-same aid (both affordable)
-interested in environmental studies (not environmental SCIENCES)
-I am considering LOCATION, QUALITY OF EDUCATION, AMOUNT OF RESOURCES, OPPORTUNITY FOR REAL LIFE EXPERIENCES!!!
Thank you all in advance 
Two months ago you were comparing Brandeis and Occidental and said that you are a future medical student. Are you still pre-med?
@lkg4answers that was for a friend… I am solely interested in environmental studies and policy!!
It would help if you clarified what you do and don’t want location-wise. Berkeley and Davis are vastly different. (I’d pick Berkeley in a heartbeat for location, but what you would look for may not be what I would look for.)
This could be literally anything. What do you actually mean? Practical experience related to your major? Student life? What?
They are both great. I’d chose Davis due to the college town and proximity to the state capitol may lend itself lots of Policy related internships and academic opportunities.
Spend some time on and around both campuses - one will stand out.
good luck.
