A price return is not the return of a fund that pays its income out. The coupon or distribution never appears in the price, so the return rows carry no winner here. VIITX currently yields 4.60% and VO 1.30%.
Volatility and max drawdown are measured over the window both funds cover: Sep 24, 2021 to Sep 22, 2026 (5 years).

Structure and taxes
VIITX is a mutual fund and VO is an ETF. A mutual fund prices once a day at net asset value and may carry a purchase minimum. An ETF trades through the day at whatever the market pays for it.
In a taxable account the difference that usually matters is distributions. An ETF can meet redemptions in kind, so it rarely has to sell holdings and rarely passes a capital gain to the people who held it; a mutual fund that sells holdings to meet redemptions can distribute a realised gain at year end to everyone still in the fund, whether or not they sold anything themselves. In a tax-deferred account that difference largely disappears. Both are descriptions of how the two wrappers work, not a recommendation.
Tax-loss harvesting works on either wrapper.
Holdings Overlap
At least 0.5% of VO's money is in holdings VIITX also owns.
Stated as a floor: for VIITX, our book for it covers 52.5% of that fund, so a holding it does not list is one we cannot count as shared. The real figure is this or higher.
We cannot see either book well enough to say how much of this pair is duplicated.
The two holdings books were reported 92 days apart, VIITX as of Apr 30, 2026 and VO as of Jul 31, 2026, so some of the difference between them is the time between the two reports rather than the funds.
