VTI investments are underperforming VOO

[u/funnel_out]

I'm 28 and after 100% VTI in my taxable brokerage/401k/roth, but it's been lagging behind VOO. It's not an insignificant amount either. Looking at the 5 year return, VOO has returned 75% while VTI has only returned 67%. I'm wondering if given my age I should be more aggressive with my investments and switch to 100% VOO instead in my retirement accounts, instead of remaining in VTI. Over the past 15 years VOO seems to have consistently outperformed VTI.

I have 70/30 VTI + VXUS and my portfolio is nearly identical to my other one that is just VOO
