<p>Definently Cornell.</p>
<p>I have lots of family that went to washu and know a lot about it. Overall, Cornell is more respected and has a much better Jewish community. I know washu has a pretty decently sized Jewish population as well, but Cornell's is hard to beat. I would advise calling up the hillel at Cornell as well.</p>
<p>This being said, the Judaic studies program might even be a little better at Cornell but I am not sure.</p>
