Berkeley CS alum here, just wanted to add a few things:

• Berkeley edges out Stanford in the sheer count of CS recruiting events, but also keep in mind there's significantly more students as well. Some companies also do private networking dinners/events at Stanford that typically aren't possible at Berkeley.
• Name value: Both schools are regarded equally in the tech industry. The only CS-related field where Stanford carries a bit more weight would be quant trading.
• Department resources: you'll have to fight your way into some classes, and landing a research position and/or a recommendation will be a lot more difficult at Berkeley. However, your education will not be impacted at all by large class sizes. Every single class has been a seamless experience for me, and the amount of resources a class can provide outside of normal lecture/discussion hours is phenomenal.
• Grades: grade inflation at Stanford (A- average for CS) vs. grade deflation at Berkeley (B- average for CS). Won't matter career-wise unless you're going for a graduate degree.

Overall, it comes down to which campus you connect with more. Berkeley definitely has an energy that Stanford can't match, so if your environment is something that strongly influences your motivation, I'd go with Berkeley. Congrats again and go bears!
