Which is better, S&P 500 or VOO?

So, you're torn between the S&P 500 and VOO, eh? Let me see... Both are solid choices, but which one's the better bet? The S&P 500, it's a tried-and-true benchmark for the US stock market, representing a diverse basket of the largest companies. But VOO, as an ETF that tracks the S&P 500, offers similar diversification with the convenience of trading like a stock. The question is, do you prefer direct exposure to the index or the flexibility of an ETF? And of course, there's always the matter of fees and expenses to consider. So, which do you think offers more bang for your buck? S&P 500 for its classic status, or VOO for its modern convenience?
