Can someone explain the differences between USFR and VMFXX?

USFR is an ETF, which means (among other things) that it trades like a stock - you can buy and sell it any time during the trading day.

VMFXX is a money market mutual fund - which means it trades once daily, after the close.

Functionally, it's not a huge difference given that both are basically cash substitutes with bonds and other yielding short term paper as the underlying assets. But if it were, say, stocks, the difference would matter more.
