How does Duke's undergrad math program compare?

<p>I know these posts are pretty old but still very relevant to many, I believe.
Can anyone make the comparison again between Berkeley and Duke in respect of
1.friendly atmosphere (to non-Christian, non Caucasian students, since they’re predominantly whites),
2.math/chemistry/economics or majors prepared for nano science at graduate level,
3.cost of living in general, and the weather all year round, and
4.any others of relevance?
Lastly, how would a visit help anyone decide?
Many thanks in anticipation.</p>
