Summer Science Program or Harvard Secondary School Program

Hi. Does anyone know which summer program is more exciting & noteworthy:
the Summer Science Program (SSP) or the Harvard Secondary School Program (ironically, also known as SSP)? For the Harvard program, I would do the 7 week option, during which students get to take classes at Harvard for actual college credit, which sounds super exciting. For the SSP program, I would do the astrophysics program, which also sounds super cool.

BTW, I can’t do both, because they’re at the same time…
