I also like SPTM, which is even cheaper than Vanguard.
You might be surprised if you compare their performance over the past 10 years:
SPTM, 2732 stocks, (0.03%), 10 yr x 11.15%/year (NAV 11.17%/year)
ITOT, 3377 stocks, (0.03%), 10 yr x 11.13%/year (NAV 11.13%/year)
VTI, 3462 stocks, (0.04%), 10 yr x 11.21%/year (NAV 11.28%/year)
I list ITOT to show it's not just the number of stocks, since ITOT has more stocks and (very slightly) worse performance than SPTM. All of these ETFs are good investments, with about the same return. But VTI must be doing something slightly different to have a (very slightly) higher performance with almost identical holdings.
