There's really no upside to continuing POW. Only downsides, lower prices, and malicious or unintended forks.
Upsides to continuing PoW, just for the sake of argument-
1. Continued free publicity via WTM/Crypto-coinZ/Crypt0-zone
2. More opportunity for small buyers to get in with less risk
3. Far easier to build a userbase and community via mining than staking.
1. Free publicity to bring more miners. Not investors, not buyers. Miners/Sellers don't invest their $$$ in a way that helps the coin. Their money goes to hardware vendors and electric companies. Then they sell/dump on the exchanges. We don't need this kind of publicity. Compare this to MN owners and Stakers, they are incentivized to first BUY, and take coins off the market and hold them. They help the community and other investors by stabilizing the price. The miners just mine and dump.
