What is the most profitable ETF?

Excuse me, but could you please elaborate on the most profitable ETF currently available in the market? I'm curious to know which one has been consistently generating the highest returns for investors. Is there a specific sector or industry that this ETF focuses on? Also, what are the risks associated with investing in it, and how does its performance compare to other similar investment options? I'm keen to make an informed decision and would appreciate your insights.
