Structure and taxes
FSKAX is a mutual fund and VTI 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.

What only one of them owns
Our book lists 12 positions for VTI that do not appear in our book for FSKAX (3.3% of the fund), and 30 for FSKAX that do not appear in VTI (1.3%).
Some of those will be the same company recorded under a different code in one of the two books, so the real difference in what you would own is no larger than this and may be smaller. We do not name the individual positions here for that reason.
