EOS is similar to Ethereum, which is 3rd ranked, but it's functionality surpasses Ethereum greatly. Cardano which is like Ethereum and 5th rank, is still stuck at less than 10 transactions per second. EOS should do about 1 million transactions per second as a smart contract platform come June 2018. It also has response times that are sub 3 seconds. If you understand programming, you'll know why that's important.
