Yes — each charges 0.09% a year. On cost there is nothing to choose between them.
Of the 99 metrics on file for both, 43 differ and the rest match. The table below lists the differences first; untick “only what differs” to see everything, including what they agree on.
Over the last twelve months SPY returned 18.6% and SPLG returned 18.4%. Those are price returns measured to the last close on file and exclude distributions, so a fund paying a larger yield looks worse on this line than it was. Past performance is not a forecast, and one year is a short window.
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.
