What is the fee on Coinbase vs Gemini?

Excuse me, could you please elaborate on the difference in fees between Coinbase and Gemini? I'm considering using one of these platforms for my cryptocurrency transactions, and I'm trying to weigh the costs and benefits. Specifically, how do the transaction fees, withdrawal fees, and any other potential charges compare between the two exchanges? It would be great if you could provide a concise yet informative comparison to help me make an informed decision.
