“I also have an interest in computer science and technology,”
Cornell is strong for these, but Berkeley is stronger.
I don’t see any reason to spend the extra $200,000 to go to Cornell. These are two great schools. If the price was the same I would see this as a hard decision but would probably go to Cornell. On the other hand I love real winters which may skew my preferences. Given how close the decision is I would be inclined to save the $200,000 for some other purpose.
