What is the best chain to transfer ETH?

I'm curious, could you please elaborate on what chain would be considered the most optimal for transferring ETH? Could you possibly weigh in on the factors that should be taken into account when making such a decision? Is there a particular chain that stands out in terms of speed, cost-effectiveness, or security? I'm also interested in hearing about any potential risks or drawbacks associated with different chains. Could you provide some insights into this, please?
