Structure and taxes
SWTSX is a mutual fund and VOO 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 8 positions for VOO that do not appear in our book for SWTSX (3.9% of the fund), and 681 for SWTSX that do not appear in VOO (9.9%).
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.
