Best summer program out of these?

<p>So I'm a junior right now and want to be enrolled in a summer program. I know people say not to do them just to look good on college applications and I'm not, but I still want it to help a little bit. My top school is USC (and then UCLA and NYU). So my questions is would it look better on my application if I attended the Summer@USC program, or would it be the same as any other program? I'm applying for COSMOS and SUMaC, but don't know if it's worth to just pay the tuition and go to the USC one instead. Please help!</p>

<p><em>Also for anyone that has gone to any of these 3, how was the experience?</em></p>
