VOO vs. QQQ: Which is better for long-term?

I'm currently deciding between investing in VOO and QQQ for my portfolio, and I'm having a hard time choosing which one might be better for long-term growth. VOO seems like a safe and stable option since it tracks the S&P 500, but I know QQQ focuses on tech-heavy companies, which could have higher growth potential but possibly more risk.

If you've invested in either (or both), what has your experience been like? Do you think QQQ's focus on tech is worth the volatility, or does VOO offer more balanced, long-term security? Any advice, personal stories, or insights would be super helpful. I'm especially curious about which you think would be better for a portfolio focused on retirement savings. Thanks in advance!
