VOO is better because it will provide a slightly better overall total return. I checked Morningstar and it showed that both VOO and IVV beat SPY in total return, mainly due to their lower expense ratios. VOO slightly edged out IVV, also. One factor that is not discussed is that SPY holds investor's dividend for a one and a half months before it actually pays it out. VOO pays its dividend in less than a week. IVV pays its dividend in about a week. Wouldn't you rather get paid ASAP or wait 1.5 months?
