The ETH platform is the most popular, but not the most efficient, EOS is faster and the Commission is smaller.
I think that EOS has no chance to fully compete with Ethereum. EOS, NEO and other is just an attempt to repeat the success of Ethereum. they offer nothing new.
You look at the number of projects that run on the platform of Ethereum and look at the number of projects that are running on other platforms ... There is no point in discussing. Ethereum is the absolute leader. To date, no project represents any serious competition for Ethereum.
