What is the best DEX on BSC?

Could you please elaborate on what you consider to be the criteria for determining the "best" decentralized exchange (DEX) on Binance Smart Chain (BSC)? Is it based on trading volume, user interface, security features, or a combination of factors? Additionally, could you provide a brief overview of the top DEXes currently operating on BSC, highlighting their unique selling points and any potential drawbacks? This information would help me better understand your question and provide a more informed answer.
