What is the best dex?

As a cryptocurrency enthusiast and investor, I'm always on the lookout for the most efficient and reliable decentralized exchange (DEX) to conduct my trades. Could you elaborate on what makes a DEX the "best" in the current market? Is it the liquidity, transaction speed, user interface, or perhaps the range of supported assets? Moreover, with the rapidly evolving landscape of decentralized finance, how do we determine which DEX is truly ahead of its competitors? I'd appreciate any insights you could provide on evaluating and comparing DEXs to find the optimal platform for my trading needs.
