What is the best inverse ETF?

I'm curious, what exactly is the best inverse ETF currently available on the market? I'm looking for an investment opportunity that allows me to profit from a potential decline in the stock market or a specific sector. Could you provide some insight into which inverse ETFs have performed well in the past and have strong potential for future gains in a downturn scenario? Also, are there any specific risks or drawbacks I should be aware of before investing in an inverse ETF?
