I will admit that I explore NEO more in-depth than Ethereum. This is because so much information is widely available for Ethereum. With NEO, there is much less. As such, I focus on explaining NEO and then comparing that explanation to Ethereums capability.
If Ethereum is Goliath, NEO is David. If Ethereum is Brad Pitt, NEO is Brad Pitts cousin, Zach Pittyounger, better dressed, and more talented but right now relegated to serving cocktails to Brad and his friends while he acts on the side. Ethereum did it first. It was revolutionary and exciting and took the crypto world by storm.
