Can I use ETH instead of WETH?

Could you please elaborate on whether it's possible to utilize ETH in lieu of WETH? I'm curious about the interchangeability of these two assets within the crypto ecosystem. Are there any specific scenarios where using ETH would be more advantageous than WETH, or vice versa? Additionally, I'm wondering if there are any potential drawbacks or limitations to substituting one for the other. Could you provide some clarity on this matter? Thank you for your assistance.
