Dimension by dimension
VOO wins on yield (1.03% vs 0.98%)
On a $10,000 investment that's about $5 more in annual dividend income before taxes — though higher yield often comes with higher risk.

Yield-trend comparison unavailable
One or both tickers are missing 5-year average yield data.
VOO is cheaper (3.00% vs 9.45%)
On a $10,000 position the lower expense ratio saves about $645/year — small annually but compounds significantly over 20+ years.
VOO is 2.2× larger by AUM
Larger funds tend to have tighter spreads, deeper liquidity, and lower closure risk.
Both pay qualified-dividend-eligible distributions
Neither is structurally flagged for ordinary-income tax treatment. Most distributions should qualify for the lower long-term capital gains rate if holding-period requirements are met.
How we compare these
Every comparison on this page is computed from current public data, not written by hand. Yield comes from the most recent dividend distribution annualized over current price. Safety scores combine yield zone, payout ratio, trend vs 5-year average, instrument type, and size — see our methodology for the exact formula. Tax-efficiency flags identify covered-call ETFs, REITs, and mREITs which distribute primarily as ordinary income.
