Hmm, from a up and down perspective both are the same, the only difference is $VTI is index that matches the whole US market, and $VOO is an index that matches only the 500 companies. If you compare them, they look the same. As they go up and down in similar percentage, it dosen't really matter which one you pick. This is my opinion from my humble experience.
