Summary: Both EOS and NEO have been billed as the ethereum-killer and both have had concerted hype machines behind them. They are both building smart contract blockchains that hope to offer the same level of service as the current Ethereum Public Blockchain but with more throughput. Scaling is the buzzword of the month and EOS and NEO aim to achieve higher transactions per second by using a delegated proof of stake or delegated Byzantine Fault Tolerance method.
