ETHE Grayscale in Schwab vs ETH in Coinbase help

Hey guys, crypto noob here. I have about $6000 worth of ETHE Grayscale in my Charles Schwab brokerage account and want to shake things up. Opinions on selling it all and then immediately purchasing $6000 worth of regular Ethereum on Coinbase? (Either way I will need to sell like $2000 pretty soon for bill payments btw)
