What is the best ETF to buy right now?

As an investor interested in the financial market, I am curious about the current state of Exchange-Traded Funds (ETFs) and wondering what would be the best ETF to buy at this moment. With the ever-changing market conditions and the influx of new ETFs, it can be overwhelming to make a decision. I understand that the best ETF depends on various factors such as investment goals, risk tolerance, and market trends. Could you please provide some insights on which ETFs are currently performing well and might be a good fit for a diversified portfolio?
