Let's not make whether a company went public a metric for assessing quality. Going public is mostly a matter of how much a company expects the public to pay to get a share for the company. Also, it is a matter of how much the bank which facilitates the offering expects to make. Currently, the markets are sky high, so even not so good companies will make crazy amounts of money for the bank and the company which went public. Just look at the dot com bubble and the IPOs for more information.
