What is the difference between ERC20 and ERC23?

[JeffBrad12]

Fees is low in Erc 23 in Erc 20 its high.

Both are same but its upgrading from old to new.

Just like car model

There are no low and high fees between ERC233 and ERC20 complaints. Because the result of how many fees for every transaction will depend on the gas calculation which already put by the sender. And how many gas price will be used by the transaction to complete the validation from the miners. You are speaking non-sense thing.
