Which USDT network is best?

Could you please elucidate which USDT network reigns supreme? I've been hearing about various options but am still uncertain as to which one offers the most reliable, secure, and efficient services. Is there a particular network that stands out in terms of transaction speed, cost-effectiveness, and overall user experience? I'm particularly interested in understanding the differences between the networks and how they might impact my cryptocurrency holdings and transactions. Your insights would be greatly appreciated.
