For me ETH because with their ERC-20 is empowering developers.

Doubtless this particular token empowers developers of all types to accurately predict how new tokens will function within the larger Ethereum system.

The impact that ERC-20 therefore has on developers is massive, as projects do not need to be redone each time a new token is released. Rather, they are designed to be compatible with new tokens, provided those tokens adhere to the rules. Developers of new tokens have by-and-large observed the ERC-20 rules, meaning that most of the tokens released through Ethereum initial coin offerings ICO are ERC-20 compliant.

Some examples of ICOs that are following this technology
