i think it all just comes down to your major. sac state and davis have a huge rivalry when it comes to football and davis always throws the "they're a state school therefore they suck" card.
however, in my major, graphic design, a degree from sac state, cal poly, even chico state, are ranked higher than an "art media" degree from davis. (I have heard some nasty stories of davis grads coming to look for design work in sacto and getting turned down... hard.)
But i mean if you want to be a doctor or cow farmer or whatever... go to davis.
And to whoever posted the comment about taking 4 years at a UC and longer at a CSU... i got out in 4 years. ::shrugs::
