Yes. VOO charges 0.03% a year against 0.09% for SPY — about $6.45 a year on every $10,000 invested. The fee is deducted from the fund's assets daily, so it is already inside every return figure on this page rather than billed separately.
Of the 99 metrics on file for both, 46 differ and the rest match. The table below lists the differences first; untick “only what differs” to see everything, including what they agree on.
Nothing stops you, but check the overlap first: the sector and holdings rows below show how much of each portfolio is the same securities in the same weights. Two funds tracking the same index are one position held twice, not diversification. This page reports the numbers and does not give investment advice.
