It will be easier to get jobs coming out of Stanford. Don't let anyone tell you otherwise. In terms of academics, Berkeley may be just as good, but if you want a high-paying job at the top law firms (any of the top 200), law school reputation is very important.
If you are a law student, the reputation of your school is more important than it is for med schools, maybe because there are more high-paying doctor jobs than high-paying lawyer jobs. In law, both grades and school reputation matter for hiring after graduation.
If you get straight A's, you can get an excellent job no matter whether you got the A's at Stanford or Berkeley. But, if you get B's, you will be much better off getting B's at Stanford than getting B's at Berkeley, in terms of the job opportunities open to you.
There is a site that people here often link to, at
informeddecisionmaking.blogspot.com
I don't really like that site, because I think it scares people away from law school by exagerrating the horrors of law school and the difficulty of finding a job. However, the part of that site that talks about school reputation on the job market, is correct--just exaggerated. So you can check it out if you want another perspective. Just keep in mind that the site exaggerates the truth.
And the lawyer above me correctly says that after your first job, your second job will be based mostly on your first job performance, and not on where you went to law school. However, from my perspective as a current law student, I think it's very important to get a good first job, so that you can have the $$ to pay the huge loans law school requires, and also because, if you get a good first job, you might not need to find a second job for a long time. Ideally, you want to stay at a firm you like, and make partner, not be bouncing from one firm to the next as an associate, with no job security.
And I think the fact that the lawyer above says that his law firm simply does NOT hire graduates of law schools ranked below 30 speaks volumes. Many firms have similar hiring policies, and so if you go to a lower-ranked school, where are you supposed to find your first job that is supposed to springboard you into your second job?
That said, Berkeley is one of the top law schools in the country, and it is good enough to get you a job at probably any law firm, if you get good grades. But if you think you might get medium or bad grades, it's better to get them at Stanford than at Berkeley.
For me, I was deciding between Columbia and Harvard. I came to Harvard, and I'm glad I did, because my law school grades are crap! But I still got a great job.
And for full disclosure: Berkeley rejected me when I applied. I got into Stanford though. So maybe that makes me biased. I don't think I'm biased, but I mention it to you just in case.
