What ETF has the best 5 year return?

I'm curious to know, among the various ETFs available in the market, which one has boasted the most impressive five-year return? Is there a particular sector or industry that this ETF focuses on that has driven its success? Or perhaps, is it a diversified portfolio that has allowed it to weather market fluctuations and emerge as a top performer? Additionally, could you provide any insights into what factors one should consider when evaluating the long-term performance of an ETF, aside from its return on investment?
