This is a fascinating topic we hope to cover in the future. Second generation tech (Ethereum) was revolutionary, but has crucial weaknesses like scalability and interoperability. As an ERC-20 token, EOS is more dependent on the specific strengths and weaknesses that Ethereum faces than Cardano. Then again, Cardano is a project that is being built slowly, with scientific peer review, and is unlikely to produce anything revolutionary for a while, possibly in 2019. Building on Ethereum, EOS should have the edge in developing speed and creating real use cases, Dapps, etc.
