1ETH = 1WETH. Here's an explanation why WETH even exists:

The ERC-20 standard defined certain mandatory rules for every token contract such as totalSupply, balanceOf, transfer, transferFrom, approve and allowance.

The ERC-20 standard was developed after the native token ETH was released, and ETH in its original form does not conform to its own ERC-20 standard.

In order to facilitate smart contract exchanges for other ERC-20 tokens on decentralised exchanges, ETH has to be first converted, or wrapped into an ERC-20 compliant version — WETH — which is a standardized format like other ERC-20 tokens.

Gas fees still apply and highly impact transactions of small amounts. Thus, in your case I'd suggest sticking to one currency and avoiding extra swaps.
