I was faculty at USC for 6 years and my answer depends on whether you're in-state or out-of-state.
For in-state students, it's an okay option. I mean, if you want the kind of college experience portrayed on TV then you should probably go to Clemson as USC, despite what the campus looks like, is really a city school. You don't have the "Animal House" type parties or anything like that. If you want the city school experience then I'd go to the College of Charleston as Charleston actually is a city where Columbia is just a collection of suburbs. But, I guess, if you're obsessed with going to a football school then you might like USC.
For out-of-state students there is no reason to go to USC. I've heard the reasons over the years why kids from (mostly the north) come to USC and they're completely wrong. The weather isn't nice. The summers are unbearable. I'll take Cleveland in January over Columbia in August. "Close to the beach that you went on vacation to with your parents?" Actually, no. The beach is a couple hours away and students always mention to me how they thought they would go all the time but never ended up doing it. Football school? Not really. They had 3 or 4 good years with Spurrier as head coach but USC has a historically terrible football team. To add to all of this, you are going to pay three times as much as an out-of-state student to go here than you would to any of your in-state schools which have the same academic reputation. Further, which nobody mentions, is how unwelcoming southerners are to northerners (and I say this because most of the out-of-state students are northerners). Southern culture is very different than northern culture and, from my experience, most northerners who have lived down here, don't like it. Further, your friend pool will be limited to other northerners as southerners don't want to mingle with you and will never really think of you as a "real gamecock" but some kind of frontrunner fake. Lastly, if you want to go greek, being from the north will make that nearly impossible.
