Can first difference estimator alleviates serial correlation in panel data?

Hi Statalist,

I am working on a state-level panel. Using -xtserial- tests for serial correlation and result is positive for serial correlation. I hope to use first differencing. If serial correlation exists in the panel, can I say the FD is more reliable than fixed effects? And why? Many thanks for your advice!
