Which way do you prefer to transfer eth specially for small amounts?
Geth consumes lots of disk space and is hell time consuming.
MEW transfer fee is so high for small amounts
You seem to be confusing wallets with fees.
Coming to wallets first, Geth is not recommended as wallet, Mist wallet has been deprecated some time back and currently the best wallets for ethereum is MEW with Metamask addon on the browser, or an Android wallet like Trust Wallet.
See these wallets are not the ones determining your fees. That depends on the congestion of the network since many people are trying to get their transactions confirmed, the load on the network is currently high and therefore to skip the line, you need to pay a higher fee to confirm your transaction quickly. You can change the fee that you pay on MEW but that would not be recommended.
Sucks but true, this problem is something inherent with ethereum currently. You can use the Binance Smart Chain to transfer but please read about it first before using it.
