According to wiki
[1] A cryptocurrency wallet is
A cryptocurrency wallet is a device,[1] physical medium,[2] program or a service which stores the public and/or private keys[3] for cryptocurrency transactions
Each wallet must be decentralized meaning that the only capable of creating and managing the private key and not any third-party member.
As for fees, wallet does not control them, but the fees vary according to the network overcrowding and therefore transactions with top fees are confirmed first, the more flexible wallet in the management of fees and predicting it are better.
The best wallet for ETH blockchain, as it is open source one which is Metamask
[2] and mycryptowallet
[3] is good options.
