Which network should I use to transfer USDC?

I'm just a bit perplexed here. Could you please clarify for me which network would be the most suitable for transferring USDC? I've heard about several options, but I'm not quite sure which one offers the best balance of speed, security, and cost-effectiveness. Would you mind guiding me through this decision-making process? I'd appreciate any insights you could share on this matter. After all, I want to make sure my transaction goes smoothly and without any hiccups. Thank you in advance for your assistance!
