I don't know the difference between VOO and all the other S&P Index funds.
The only index I really like is RSP. It equal weights the index and doesn't just sell you another tech fund in drag.
Buffet has a HUGE advantage over mutual funds and individuals. He doesn't fall under the same reporting standards of a mutual fund and he's big enough that companies come to him with information before the street gets it. I didn't say he recommends individual stocks, I said he buys them over indexes. If an index ETF was the all in end all way to invest, it's where all his money would be. I don't like the idea that Buffet can dump all his MSFT if he wants to, but in an index fund I'm left holding his bag. SURE he wants YOU in an index.
