VOO vs CSPX
VOO and CSPX both provide S&P 500 exposure, but their fund structure, listing market, dividend treatment, and tax considerations can differ.
Key differences
VOO trades in the United States and distributes dividends. CSPX is commonly used as an accumulating UCITS share class by non-U.S. investors. Domicile, withholding tax, estate tax exposure, fees, spreads, broker access, and currency handling can all matter.

A fair VOO vs CSPX DCA backtest should use the same monthly investment amount and the same start and end years. The result shows one historical period, not a universal winner.
Risk and limitations
Neither ETF is always better. Results depend on time period, fund fees, taxes, exchange rates, dividends, tracking difference, data availability, and market performance. This is educational only and not financial advice.
