VUG or VOO?

and which one from there Midcaps

VXF
VO
VOT
VOE

I just do VTI, but I'm lazy.

VOO is a great core holding.  I always have at least 50% VOO as my core.  On the large cap side I use VUG or IWD depending on how I feel the market is heading.  VOE is a great mid cap option.  For years I paid professionals to manage my holdings, and honestly none could beat VOO over the longer haul.  The S&P 500 is the benchmark everything is judged against.  You could do a lot worse then just putting everything in VOO and forgetting about it.
