A three-way cage match over one basis point: VOO and IVV at 0.03%, SPLG at 0.02%. Same index, enormous, liquid, and performance differences are noise.

- Pick whichever is cheapest the day you buy, then stop thinking about it - Options traders: none of these; SPY owns that job with its deeper options market - Tiebreaker that matters: securities lending and tracking error history, not a basis point of fee - This comparison is a distraction from decisions worth a hundred times more: your stock-bond mix, your monthly contribution - Perfecting a one-basis-point gap while sitting on 20% cash is rearranging deck chairs

Overlap ($4.99 one-time) runs the three-way comparison with overlap and returns attached, if you still want the numbers.
