What is the difference between gold ETF and PAXG?

Could you elaborate on the key differences between a gold Exchange-Traded Fund (ETF) and the Physically-Backed Audited Gold (PAXG) token? As an investor in the cryptocurrency and finance space, I'm curious to understand how these two assets differ in terms of their underlying value, liquidity, auditability, and potential returns. Does the PAXG token offer any unique advantages over traditional gold ETFs in terms of accessibility, transparency, or price efficiency? I'd appreciate a concise comparison that highlights the key points of distinction.
