Which type of token is better. ERC 20 or a unique one, for me that is good which gives tangible results. and I am more inclined to ERC 20. Even though many programs now use unique wallet numbers.

Tokens are based on major coins blockchains. ERC-20 tokens are tokens that are based on Ethereum blockchain and you can store them on any Ethereum wallet. NEP-5 tokens are tokens that are based on NEO blockchain and could be stored in a NEO wallet. However, ETH and NEO are coins.
