Caltech vs Stanford vs UCSD

[burgundywave]

Hey y'all,

I was lucky enough to be accepted to UCSD (Scripps) and Caltech and invited to visit Stanford for a prospective student weekend . I haven't been officially accepted to Stanford yet but if I am I want to be prepared to make my decision! I will be visiting all 3 schools in February.

If I could I would attend all of them as they are all very good research fit, I could see myself living in each city and they are offering similarly generous funding packages (assuming Stanford would offer me a similar package). 

So, in your opinion, which school offers the best overall grad school experience?

I'm applying to geophysics PhD programs. 

Thanks
