SSP or BWSI?

I’m interested in majoring in physics or engineering in college (possibly a double major?). Recently, I was accepted to the Beaverworks Summer Institute CogWorks program, and to the SSP astrophysics program. Here are the links to the programs:
https://beaverworks.ll.mit.edu/CMS/bw/bwsi
https://summerscience.org/

There is plenty of information on SSP, but I haven’t able to find much on beaverworks. Could anyone who’s attend provide any information on their experience? Right now I’m leaning towards SSP because people seem to enjoy it, but I think that I’d have a great experience at either program. Any help would be appreciated, because I only have a few days to decide which one to pick.
Thanks!
